2015-05-28Combine bootm_find_<thing> functions togetherKarl Apsite
bootm_find_ramdisk_fdt() renamed to bootm_find_images() for readability. The function bootm_find_ramdisk_fdt() appears to be a simple wrapper for bootm_find_ramdisk(), bootm_find_fdt(), and now bootm_find_loadables(). I didn't see any other callers entering a bootm_find<thing>, so removing the wrapper, and condensing these together hopefully makes the code a little simpler.

2014-08-30cmd_bootm.c: Add 'booti' for ARM64 Linux kernel ImagesTom Rini
The default format for arm64 Linux kernels is the "Image" format, described in Documentation/arm64/booting.txt. This, along with an optional gzip compression on top is all that is generated by default. The Image format has a magic number within the header for verification, a text_offset where the Image must be run from, an image_size that includes the BSS and reserved fields. This does not support automatic detection of a gzip compressed image. Signed-off-by: Tom Rini <trini@ti.com>

2014-05-08image: add support for Android's boot image formatSebastian Siewior
This patch adds support for the Android boot-image format. The header file is from the Android project and got slightly alterted so the struct + its defines are not generic but have something like a namespace. The header file is from bootloader/legacy/include/boot/bootimg.h. The header parsing has been written from scratch and I looked at bootloader/legacy/usbloader/usbloader.c for some details. The image contains the physical address (load address) of the kernel and ramdisk. This address is considered only for the kernel image. The "second image" defined in the image header is currently not supported. I haven't found anything that is creating this. v3 (Rob Herring): This is based on http://patchwork.ozlabs.org/patch/126797/ with the following changes: - Rebased to current mainline - Moved android image handling to separate functions in common/image-android.c - s/u8/char/ in header to fix string function warnings - Use SPDX identifiers for licenses - Cleaned-up file source information: android_image.h is from file include/boot/bootimg.h in repository: https://android.googlesource.com/platform/bootable/bootloader/legacy The git commit hash is 4205b865141ff2e255fe1d3bd16de18e217ef06a usbloader.c would be from the same commit, but it does not appear to have been used for any actual code. v4: - s/andriod/android/ - Use a separate flag ep_found to track if the entry point has been set rather than using a magic value.

2014-01-14bootm: Reinstate special case for standalone imagesSimon Glass
For standalone images, bootm had a special case where the OS boot function was NULL but did actually exist. It was just called manually. This was removed by commit 35fc84fa which checks for the non-existence of this function before the special case is examined. There is no obvious reason why standalone is handled with a special case. Adjust the code so that standalone has a normal OS boot function. We still need a special case for when the function returns, but at least we can avoid the main problem. This is intended to fix the reported: ERROR: booting os 'U-Boot' (17) is not supported but needs testing. Signed-off-by: Simon Glass <sjg@chromium.org>

functions In commit "5c427e4: use BOOTM_STATE_OS_CMDLINE flag for plain bootm" and "3d187b3: Only pass BOOTM_STATE_OS_CMDLINE on PowerPC/MIPS", BOOTM_STATE_OS_CMDLINE was added to do_bootm for PowerPC and MIPS. This breaks other OSes (vxworks, netbsd, plan9,...) that don't support subcommand processing, e.g. they all contain the following code in their do_bootm_xxx(): if (flag & BOOTM_STATE_OS_PREP) return 0; if ((flag != 0) && (flag != BOOTM_STATE_OS_GO)) return 1; which will result a "subcommand not supported" error.

However, this is only valid / useful on PowerPC and MIPS, and causes a problem on ARM where we specifically do not use it. Rather than make this state fake pass like we do for GO on some arches (which need updating to use the GO state), we should just not pass CMDLINE except when it may be used, like before.

2013-09-20Fix loading freeze when netconsole is activeFrederic Leroy
Netconsole calls eth_halt() before giving control to another operating system. But the state machine of netconsole don't take it into account. Thus, netconsole calls network functions of an halted network device, making the whole system freeze. Rather than modifying the state machine of netconsole, we just unregister the current network device before booting. It does work because nc_send_packet() verifies that the current network device is not null. Signed-off-by: Frédéric Leroy <fredo@starox.org>
2013-09-20bootm: use BOOTM_STATE_OS_CMDLINE flag for plain bootmPaul Burton
A plain bootm used to call the architecture specific boot function with no flags, but was modified by commit 35fc84fa "Refactor the bootm command to reduce code duplication" to call the architecture specific boot function multiple times with various flags in sequence. The BOOTM_STATE_OS_CMDLINE flag was not used, indeed it seems that at least ARM prepares the command line on BOOTM_STATE_OS_PREP. However on MIPS since commit 59e8cbdb "MIPS: bootm: refactor initialisation of kernel cmdline" the command line is not prepared in response to a BOOTM_STATE_OS_PREP flag, only on BOOTM_STATE_OS_CMDLINE or a call with no flags. The end result is that a combination of those 2 commits leads to MIPS boards booting kernels with no command line arguments. An extra invocation of the architecture specific boot function with BOOTM_STATE_OS_CMDLINE fixes this. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

2013-07-17bootm: Move fixup_silent_linux() earlier in the bootm stagesSimon Glass
Before the bootm refactor, fixup_silent_linux() was done only in the monolithic bootm case, not in the subcommand case. With the refactor, it is done always, which is good. Unfortunately it is done too late, since it is the PREP or CMDLINE stages that set up the command line for Linux.

2013-07-12bootm: Use selected configuration for ramdisk and fdtSimon Glass
If a specific configuraion is selected by the bootm command, e.g. with 'bootm 84000000#recoveryconf' we must honour this for not just the kernel, but also the ramdisk and FDT. In the conversion to using a common fit_image_load() function for loading images from FITs (commits a51ec63 and 53f375f) this feature was lost. Reinstate it by passing the selected configuration back from fit_image_load() to boot_get_kernel(), then use this configuration (which is stored in images->fit_uname_cfg) in both boot_get_ramdisk() and boot_get_fdt().

If we re-order the checks (and make them slightly clearer as well) the warning goes away. bootm_load_os may only return 0 on success, BOOTM_ERR_OVERLAP in a non-fatal overlap (already covered in comments) or a fatal BOOTM_ERR that is covered in the error handler.

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.

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.

2013-06-26Clarify bootm OS argumentsSimon Glass

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.
