2013-06-30usb, g_dnl: make possibility to fixup the device_desc board specificHeiko Schocher
add a weak dummy function g_dnl_fixup to add the possibility to update the device_desc board specific. Used on the upcoming siemens board support, where idVendor and idProduct is stored in an eeprom.

2013-06-30usb, dfu gadget: switch to dfu mode in dfu_bindHeiko Schocher
- set in to_dfu_mode() f_dfu->dfu_state = DFU_STATE_dfuIDLE as after every to_dfu_mode call this is done, so move this into to_dfu_mode - switch in dfu_bind() into dfu mode: This fixes wrong "dfu-util -l" output, when calling "dfu-util -l" after a board reset, without doing a download before.

2013-06-28Fix bootm to work on powerpc again (compressed uImage)Stefan Roese
Patch 35fc84fa1 [Refactor the bootm command to reduce code duplication] breaks booting Linux (compressed uImage with fdt) on powerpc. boot_jump_linux() mustn't be called before boot_prep_linux() and boot_body_linux() have been called. So remove the superfluous call to boot_jump_linux() in arch/powerpc/lib/bootm.c as its called later on in this function.

2013-06-28mkimage: Build signing only if board has CONFIG_FIT_SIGNATURESimon Glass
At present mkimage is set up to always build with image signing support. This means that the SSL libraries (e.g. libssl-dev) are always required. Adjust things so that mkimage can be built with and without image signing, controlled by the presence of CONFIG_FIT_SIGNATURE in the board config file. If CONFIG_FIT_SIGNATURE is not enabled, then mkimage will report a warning that signing is not supported. If the option is enabled, but libraries are not available, then a build error similar to this will be shown: lib/rsa/rsa-sign.c:26:25: fatal error: openssl/rsa.h: No such file or directory Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-28bootm: Disable interrupts before loading OSSimon Glass
This restores the ordering of interrupt disable to what it what before commit 35fc84fa. It seems that on some archiectures (e.g. PowerPC) the OS is loaded into an interrupt region, which can cause problems if interrupts are still running.

2013-06-28cmd_bootm.c: Correct BOOTM_ERR_OVERLAP handlingTom Rini
With 35fc84fa1 [Refactor the bootm command to reduce code duplication] we stopped checking the return value of bootm_load_os (unintentionally!) and simply returned if we had a non-zero return value from the function. This broke the valid case of a legacy image file of a single kernel loaded into an overlapping memory area (the default way of booting nearly all TI platforms). The best way to fix this problem in the new code is to make bootm_load_os be the one to see if we have a problem with this, and if it's fatal return BOOTM_ERR_RESET and if it's not BOOTM_ERR_OVERLAP, so that we can avoid calling lmb_reserve() but continue with booting. We however still need to handle the other BOOTM_ERR values so re-work do_bootm_states so that we have an error handler at the bottom we can goto for problems from bootm_load_os, or problems from the other callers (as the code was before). Add a comment to do_bootm_states noting the existing restriction on negative return values. Signed-off-by: Tom Rini <trini@ti.com> --- Changes in v2: - Rework so that only bootm_load_os and boot_selected_os head down into the err case code, and other errors simply return back to the caller. Fixes 'spl export'.

2013-06-26Fix block device accesses beyond 2TiBSascha Silbe
With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives. For some obscure reason, the current U-Boot code uses lbaint_t for the number of blocks to read (a rather optimistic estimation of how RAM sizes will evolve), but not for the starting address. Trying to access blocks beyond the 2TiB boundary will simply wrap around and read a block within the 0..2TiB range. We now use lbaint_t for block start addresses, too. This required changes to all block drivers as the signature of block_read(), block_write() and block_erase() in block_dev_desc_t changed. Signed-off-by: Sascha Silbe <t-uboot@infra-silbe.de>
2013-06-26cmd_bootm: Add command line arguments to Plan 9Steven Stallion

2013-06-26Add verified boot information and testSimon Glass
Add a description of how to implement verified boot using signed FIT images, and a simple test which verifies operation on sandbox. The test signs a FIT image and verifies it, then signs a FIT configuration and verifies it. Then it corrupts the signature to check that this is detected.

2013-06-26sandbox: config: Enable FIT signatures with RSASimon Glass
We want to sign and verify images using sandbox, so enable these options. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26image: Add support for signing of FIT configurationsSimon Glass
While signing images is useful, it does not provide complete protection against several types of attack. For example, it it possible to create a FIT with the same signed images, but with the configuration changed such that a different one is selected (mix and match attack). It is also possible to substitute a signed image from an older FIT version into a newer FIT (roll-back attack). Add support for signing of FIT configurations using the libfdt's region support. Please see doc/uImage.FIT/signature.txt for more information. Signed-off-by: Simon Glass <sjg@chromium.org>

2013-06-26mkimage: Add -r option to specify keys that must be verifiedSimon Glass
Normally, multiple public keys can be provided and U-Boot is not required to use all of them for verification. This is because some images may not be signed, or may be optionally signed. But we still need a mechanism to determine when a key must be used. This feature cannot be implemented in the FIT itself, since anyone could change it to mark a key as optional. The requirement for key verification must go in with the public keys, in a place that is protected from modification. Add a -r option which tells mkimage to mark all keys that it uses for signing as 'required'. If some keys are optional and some are required, run mkimage several times (perhaps with different key directories if some keys are very secret) using the -F flag to update an existing FIT.

2013-06-26mkimage: Add -c option to specify a comment for key signingSimon Glass

2013-06-26mkimage: Add -F option to modify an existing .fit fileSimon Glass
When signing images it is sometimes necessary to sign with different keys at different times, or make the signer entirely separate from the FIT creation to avoid needing the private keys to be publicly available in the system. Add a -F option so that key signing can be a separate step, and possibly done multiple times as different keys are avaiable.

2013-06-26mkimage: Add -K to write public keys to an FDT blobSimon Glass
FIT image verification requires public keys. Add a convenient option to mkimage to write the public keys to an FDT blob when it uses then for signing an image. This allows us to use: mkimage -f test.its -K dest.dtb -k keys test.fit and have the signatures written to test.fit and the corresponding public keys written to dest.dtb. Then dest.dtb can be used as the control FDT for U-Boot (CONFIG_OF_CONTROL), thus providing U-Boot with access to the public keys it needs.

2013-06-26image: Add RSA support for image signingSimon Glass
RSA provides a public key encryption facility which is ideal for image signing and verification. Images are signed using a private key by mkimage. Then at run-time, the images are verified using a private key. This implementation uses openssl for the host part (mkimage). To avoid bringing large libraries into the U-Boot binary, the RSA public key is encoded using a simple numeric representation in the device tree. Signed-off-by: Simon Glass <sjg@chromium.org>

2013-06-26Add a 'fake' go command to the bootm commandSimon Glass
For tracing it is useful to run as much of U-Boot as possible so as to get a complete picture. Quite a bit of work happens in bootm, and we don't want to have to stop tracing before bootm starts. Add a way of doing a 'fake' boot of the OS - which does everything up to the point where U-Boot is about to jump to the OS image. This allows tracing to record right until the end. This requires arch support to work. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26Refactor the bootm command to reduce code duplicationSimon Glass
At present the bootm code is mostly duplicated for the plain 'bootm' command and its sub-command variant. This makes the code harder to maintain and means that changes must be made to several places. Introduce do_bootm_states() which performs selected portions of the bootm work, so that both plain 'bootm' and 'bootm <sub_command>' can use the same code. Additional duplication exists in bootz, so tidy that up as well. This is not intended to change behaviour, apart from minor fixes where the previously-duplicated code missed some chunks of code. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26Clarify bootm OS argumentsSimon Glass
At present the arguments to bootm are processed in a somewhat confusing way. Sub-functions must know how many arguments their calling functions have processed, and the OS boot function must also have this information. Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in the same way. Adjust the code so that arguments are removed from the list before calling a sub-function. This means that all functions can know that argv[0] is the first argument of which they need to take notice. Signed-off-by: Simon Glass <sjg@chromium.org>
