2017-07-27spl: make SPL and normal u-boot stage use independent SYS_MALLOC_F_LENAndy Yan
Some platforms have very limited SRAM to run SPL code, so there may not be the same amount space for a malloc pool before relocation in the SPL stage as the normal U-Boot stage. Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.

2017-05-22lib: move hash CONFIG options to KconfigTom Rini
Commit 94e3c8c4fd7b ("crypto/fsl - Add progressive hashing support using hardware acceleration.") created entries for CONFIG_SHA1, CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL. However, no defconfig has migrated to it. Complete the move by first adding additional logic to various Kconfig files to select this when required and then use the moveconfig tool. In many cases we can select these because they are required to implement other drivers. We also correct how we include the various hashing algorithms in SPL. This commit was generated as follows (after Kconfig additions): [1] tools/moveconfig.py -y SHA1 SHA256 SHA_HW_ACCEL [2] tools/moveconfig.py -y SHA_PROG_HW_ACCEL Note: We cannot move SHA_HW_ACCEL and SHA_PROG_HW_ACCEL simultaneously because there is dependency between them.

2017-05-17SPL: FIT: allow loading multiple imagesAndre Przywara
So far we were not using the FIT image format to its full potential: The SPL FIT loader was just loading the first image from the /images node plus one of the listed DTBs. Now with the refactored loader code it's easy to load an arbitrary number of images in addition to the two mentioned above. As described in the FIT image source file format description, iterate over all images listed at the "loadables" property in the configuration node and load every image at its desired location. This allows to load any kind of images: - firmware images to execute before U-Boot proper (for instance ARM Trusted Firmware (ATF)) - firmware images for management processors (SCP, arisc, ...) - firmware images for devices like WiFi controllers - bit files for FPGAs - additional configuration data - kernels and/or ramdisks The actual usage of this feature would be platform and/or board specific. Also update the FIT documentation to mention the new SPL feature and provide an example .its file to demonstrate its features.

2017-05-17SPL: FIT: rework U-Boot image loadingAndre Przywara
Currently the SPL FIT loader always looks only for the first image in the /images node a FIT tree, which it loads and later executes. Generalize this by looking for a "firmware" property in the matched configuration subnode, or, if that does not exist, for the first string in the "loadables" property. Then using the string in that property, load the image of that name from the /images node. This still loads only one image at the moment, but refactors the code to allow extending this in a following patch. To simplify later re-usage, we also generalize the spl_fit_select_index() function to not return the image location, but just the node offset.

2017-05-17SPL: FIT: refactor FDT loadingAndre Przywara
Currently the SPL FIT loader uses the spl_fit_select_fdt() function to find the offset to the right DTB within the FIT image. For this it iterates over all subnodes of the /configuration node in the FIT tree and compares all "description" strings therein using a board specific matching function. If that finds a match, it uses the string in the "fdt" property of that subnode to locate the matching subnode in the /images node, which points to the DTB data. Now this works very well, but is quite specific to cover this particular use case. To open up the door for a more generic usage, let's split this function into: 1) a function that just returns the node offset for the matching configuration node (spl_fit_find_config_node()) 2) a function that returns the image data any given property in a given configuration node points to, additionally using a given index into a possbile list of strings (spl_fit_select_index()) This allows us to replace the specific function above by asking for the image the _first string of the "fdt" property_ in the matching configuration subnode points to. This patch introduces no functional changes, it just refactors the code to allow reusing it later. (diff is overly clever here and produces a hard-to-read patch, so I recommend to throw a look at the result instead).

ATF(ARM Trusted Firmware) is used by ARM arch64 SoCs, find more infomation about ATF at: https://github.com/ARM-software/arm-trusted-firmware SPL is considered as BL2 in ATF terminology, it needs to load other parts of ATF binary like BL31, BL32, SCP-BL30, and BL33(U-Boot). And needs to prepare the parameter for BL31 which including entry and image information for all other images. Then the SPL handle PC to BL31 with the parameter, the BL31 will do the rest of work and at last get into U-Boot(BL33). This patch needs work with patches from Andre for SPL support multi binary in FIT.

2017-01-29ARM: uniphier: change CONFIG_SPL_PAD_TO to 128KBMasahiro Yamada
The Boot ROM supports authentication feature to prevent malformed software from being run on products. The signature is added at the tail of the second stage loader (= SPL in U-boot terminology). The size of the second stage loader was 64KB, and it was consistent across SoCs. The situation changed when LD20 SoC appeared; it loads 80KB second stage loader, and it is the only exception. Currently, CONFIG_SPL_PAD_TO is set to 64KB and U-Boot proper is loaded from the 64KB offset of non-volatile devices. This means the signature of LD20 SoC (located at 80KB offset) corrupts the U-Boot proper image. Let's move the U-Boot proper image to 128KB offset. It uses 48KB for nothing but padding, and we could actually locate the U-Boot proper at 80KB offset. However, the power of 2 generally seems a better choice for the offset address.

2017-01-28Revert "armv8: release slave cores from CPU_RELEASE_ADDR"Masahiro Yamada
This reverts commit 8c36e99f211104fd7dcbf0669a35a47ce5e154f5. There is misunderstanding in commit 8c36e99f2111 ("armv8: release slave cores from CPU_RELEASE_ADDR"). How to bring the slave cores into U-Boot proper is platform-specific. So, it should be cared in SoC/board files instead of common/spl/spl.c. As you see SPL is the acronym of Secondary Program Loader, there is generally something that runs before SPL (the First one is usually Boot ROM). How to wake up slave cores from the Boot ROM is really SoC specific. So, the intention for the spin table support is to bring the slave cores into U-Boot proper in an SoC specific manner. (this must be done after relocation. see below.) If you bring the slaves into SPL, it is SoC own code responsibility to transfer them to U-Boot proper. The Spin Table defines the interface between a boot-loader and Linux kernel. It is unrelated to the interface between SPL and U-Boot proper. One more thing is missing in the commit; spl_image->entry_point points to the entry address of U-Boot *before* relocation. U-Boot relocates itself between board_init_f() and board_init_r(). This means the master CPU sees the different copy of the spin code than the slave CPUs enter. The spin_table_update_dt() protects the code *after* relocation. As a result, the slave CPUs spin in unprotected code, which leads to unstable behavior. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2017-01-14armv8: release slave cores from CPU_RELEASE_ADDROded Gabbay
When using ARMv8 with ARMV8_SPIN_TABLE=y, we want the slave cores to wait on spin_table_cpu_release_addr, until the Linux kernel will "wake" them by writing to that location. The address of spin_table_cpu_release_addr is transferred to the kernel using the device tree that is updated by spin_table_update_dt(). However, if we also use SPL, then the slave cores are stuck at CPU_RELEASE_ADDR instead and as a result, never wake up. This patch releases the slave cores by writing spl_image->entry_point to CPU_RELEASE_ADDR location before the end of the SPL code (at jump_to_image_no_args()). That way, the slave cores will start to execute the u-boot and will get to the spin-table code and wait on the correct address (spin_table_cpu_release_addr).
