2017-11-26spl: atf: introduce spl_invoke_atf and make bl31_entry privatePhilipp Tomsich
This adds a new interface spl_invoke_atf() that takes a spl_image_info argument and then derives the necessary parameters for the ATF entry. Based on the additional information recorded (into /fit-images) from the FIT loadables, we can now easily locate the next boot stage. We now pass a pointer to a FDT as the platform-specific parameter pointer to ATF (so we don't run into the future headache of every board/platform defining their own proprietary tag-structure), as FDT access is already available in ATF. With the necessary infrastructure in place, we can now update the support for the ARM Trusted Firmware to dispatch into the spl_invoke_atf function only if a IH_OS_ARM_TRUSTED_FIRMWARE image is loaded.

2017-10-09spl: fix assignment of board info to global dataYork Sun
Commit 15eb1d43bf47 ("spl: reorder the assignment of board info to global data") intended to move assignment of board info earlier, into board_init_r(). However, function preload_console_init() is called either from spl_board_init() or from board_init_f(). For the latter case, the board info assignment is much earlier than proposed board_init_r().

Even though there's now a TPL_DM configuration option, the spl logic still checks for SPL_DM and thus does not pick up the proper config option.

2017-05-15spl: add support to booting with ATFKever Yang
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. The entry point of bl31 and bl33 are still using hard code because we still can not get them from the FIT image information.

At present malloc_base/_limit/_ptr are not initialised in spl_init() when we call spl_init() in board_init_f(). This is due to a recent change aimed at avoiding overwriting the malloc area set up on some boards by spl_relocate_stack_gd(). However if CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN is not defined, we now skip setting up the memory area in spl_init() which is obviously wrong.

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).

2016-12-02dm: core: Handle global_data moving in SPLSimon Glass
When CONFIG_SPL_STACK_R is enabled, and spl_init() is called before board_init_r(), spl_relocate_stack_gd() will move global_data to a new place in memory. This affects driver model since it uses a list for the uclasses. Unless this is updated the list will become invalid. When looking for a non-existent uclass, such as when adding a new one, the loop in uclass_find() may continue forever, thus causing a hang. Add a function to correct this rather obscure bug.
