* ARM: uniphier: change CONFIG_SPL_PAD_TO to 128KBMasahiro Yamada2017-01-29-2/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

* Revert "armv8: release slave cores from CPU_RELEASE_ADDR"Masahiro Yamada2017-01-28-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* spl: Remove overwrite of relocated malloc limitAndrew F. Davis2017-01-28-1/+6
| | | | | | | | | | | spl_init on some boards is called after stack and heap relocation, on some platforms spl_relocate_stack_gd is called to handle setting the limit to its value CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN when simple SPL malloc is enabled during relocation. spl_init should then not re-assign the old pre-relocation limit when this is defined.

* armv8: release slave cores from CPU_RELEASE_ADDROded Gabbay2017-01-14-0/+8
| | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | 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.
