| * | | armv8/fsl-lsch3: Update early MMU tableYork Sun2015-04-23-17/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During booting, IFC is mapped to low region. After booting up, IFC is remapped to high region for larger space. The environmental variables are also stored at high region. In order to read the variables during booting, a virtual mapping is required. Cache was enabled for entire IFC space before. Actually the first two entries are big enough (4MB) to cover the boot code and environmental variables. Remove extra entries. Move OCRAM entry out of ifdef.

| * | | armv8/ls2085a: Fix generic timer clock sourceYork Sun2015-04-23-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The timer clock is system clock divided by 4, not fixed 12MHz. This is common to the SoC, not board specific. Primary core is fixed when u-boot still runs in board_f. Secondary cores are fixed by reading a variable set by u-boot.

Move them out of common header file and placed into respective board header files. Move TEXTBASE to 1MB offset to fit NOR flash with up to 1MB sector size. Enable command auto complete. Update prompt symbol. Set fdt_high to 0xa0000000 because Linux requires that the fdt be 8-byte aligned and below 512 MiB. Besides ensuring compliance with the 512 MiB limit, this avoids problems with the dtb being misaligned within the FIT image. Change the MC FW, MC DPL and Debug server NOR addresses in compliance with the NOR flash layouts for 128MB flash. Add PCIe macros. Enable "loadb" command. Disable debug server. Enable workaround for erratum A008511. Stop reset on panic for postmortem debugging.

Boot Script can contain esbc_validate commands and bootm command. Uboot source command used in default secure boot command will run the bootscript. 4. Command esbc_halt added to ensure either bootm executes after validation of images or core should just spin.

(Please note this is not a bug of Kconfig.) We should not do so unless we have a special reason. Actually, for CONFIG_DM*, we have no good reason to do so. Generally, CONFIG_DM is not a user-configurable option. Once we convert a driver into Driver Model, the board only works with Driver Model, i.e. CONFIG_DM must be always enabled for that board. So, using "select DM" is more suitable rather than allowing users to modify it. Another good thing is, Kconfig warns unmet dependencies for "select" syntax, so we easily notice bugs. Actually, CONFIG_DM and other related options have been added without consistency: some into arch/*/Kconfig, some into board/*/Kconfig, and some into configs/*_defconfig. This commit prefers "select" and cleans up the following issues. [1] Never use "CONFIG_DM=n" in defconfig files It is really rare to add "CONFIG_FOO=n" to disable CONFIG options. It is more common to use "# CONFIG_FOO is not set". But here, we do not even have to do it. Less than half of OMAP3 boards have been converted to Driver Model. Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is weird. Instead, add "select DM" only to appropriate boards, which eventually eliminates "CONFIG_DM=n", etc. [2] Delete redundant CONFIGs Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again in configs/sandbox_defconfig. Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and defines it also in omap3_beagle_defconfig and devkit8000_defconfig. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
