2017-02-12flash: complete CONFIG_SYS_NO_FLASH move with renamingMasahiro Yamada
We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is not completed. Finish this work by the tool. During this move, let's rename it to CONFIG_MTD_NOR_FLASH. Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH" than those of "#ifdef CONFIG_SYS_NO_FLASH". Flipping the logic will make the code more readable. Besides, negative meaning symbols do not fit in obj-$(CONFIG_...) style Makefiles. This commit was created as follows: [1] Edit "default n" to "default y" in the config entry in common/Kconfig. [2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH" [3] Rename the instances in defconfigs by the following: find . -path './configs/*_defconfig' | xargs sed -i \ -e '/CONFIG_SYS_NO_FLASH=y/d' \ -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/' [4] Change the conditionals by the following: find . -name '*.[ch]' | xargs sed -i \ -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \ -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \ -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \ -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/' [5] Modify the following manually - Rename the rest of instances - Remove the description from README - Create the new Kconfig entry in drivers/mtd/Kconfig - Remove the old Kconfig entry from common/Kconfig - Remove the garbage comments from include/configs/*.h Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2016-07-21powerpc/mpc85xx: T104x: Add nand secure boot targetSumit Garg
For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC. In non-secure boot scenario from NAND, this address will map to CPC configured as SRAM. But in case of secure boot, this default address always maps to IBR (Internal Boot ROM). The IBR code requires that the bootloader(U-boot) must lie in 0 to 3.5G address space i.e. 0x0 - 0xDFFFFFFF. For secure boot target from NAND, the text base for SPL is kept same as non-secure boot target i.e. 0xFFFx_xxxx but the SPL U-boot binary will be copied to CPC configured as SRAM with address in 0-3.5G(0xBFFC_0000) As a the virtual and physical address of CPC would be different. The virtual address 0xFFFx_xxxx needs to be mapped to physical address 0xBFFx_xxxx. Create a new PBI file to configure CPC as SRAM with address 0xBFFC0000 and update DCFG SCRTACH1 register with location of Header required for secure boot. The changes are similar to commit 467a40dfe35f48d830f01a72617207d03ca85b4d powerpc/mpc85xx: SECURE BOOT- NAND secure boot target for P3041 While P3041 has a 1MB CPC and does not require SPL. On T104x, CPC is only 256K and thus SPL framework is used. The changes are only applicable for SPL U-Boot running out of CPC SRAM and not the next level U-Boot loaded on DDR.

This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.
