* ARM: UniPhier: move EEPROM device node into a separate DTSMasahiro Yamada2015-02-07-20/+23
| | | | | | | | | This EEPROM chip is installed on the expansion board commonly used on UniPhier platform. To avoid duplicated description, move the EEPROM node to a separate file and include it from other device tree sources. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: remove dummy gpio.hMasahiro Yamada2015-02-07-6/+0
| | | | | | | | | | This dummy header was introduced by commit 630bf80ebb34 (ARM: UniPhier: add dummy gpio.h to enable CONFIG_OF_CONTROL). Thanks to commit a08d643dbd85 (dm: Drop gpio.h header from fdtdec.c), such an ugly workaround is no longer needed. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

| | | | | | | | | | | | | | | | | | | | In f0c3a6c we stopped setting gd in board_init_f, but later had to revert to due problems on certain platforms. As davinci does not look to have these problems, we can drop the setting here and rely upon crt0.S to do it. Cc: Peter Howard <pjh@northern-ridge.com.au> Signed-off-by: Tom Rini <trini@ti.com>

| * ARM: OMAP5: DRA7xx: Add support for power rail groupingLubomir Popov2015-01-29-28/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the DRA72x (J6Eco) EVM one PMIC SMPS is powering three SoC core rails. This concept of using one SMPS to supply multiple core domains (in various, although limited combinations, per primary device use case) has now become common and is used by many customer J6/J6Eco designs; it is supported by a number of corresponding PMIC OTP versions. This patch implements correct operation of the core voltages scaling routine by ensuring that each SMPS that is supplying more than one domain shall be written only once, and with the highest voltage of those fused in the SoC (or of those defined in the corresponding header if fuse read is disabled or fails) for the power rails belonging to the group. The patch also replaces some PMIC-related magic numbers with the appropriate definitions. The default OPP_NOM voltages for the DRA7xx SoCs are updated as well, per the latest DMs. Signed-off-by: Lubomir Popov <l-popov@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Where the mips32 & mips64 implementations of start.S differ in terms of access sizes & offsets, use the appropriate macros from asm.h to abstract those differences away. This is in preparation for sharing a single copy of start.S between mips32 & mips64. The exception to this is loads of immediates to be written to the cop0 Config register, which is a 32bit register on mips64 and therefore constants written to it can be loaded as such.

| * | MIPS: clear TagLo select 2 during cache initPaul Burton2015-01-29-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current MIPS cores from Imagination Technologies use TagLo select 2 for the data cache. The architecture requires that it is safe for software to write to this register even if it isn't present, so take the trivial option of clearing both selects 0 & 2.

| * | MIPS: allow systems to skip loads during cache initPaul Burton2015-01-29-6/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current MIPS systems do not require that loads be performed to force the parity of cache lines, a simple invalidate by clearing the tag for each line will suffice. Thus this patch makes the loads & subsequent second invalidation conditional upon the CONFIG_SYS_MIPS_CACHE_INIT_RAM_LOAD option, and defines that for existing mips32 targets. Exceptions are malta where this is known to be unnecessary, and qemu-mips where caches are not implemented.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mips_init_[id]cache functions are small & only called once from a single callsite. Inlining them allows mips_cache_reset to avoid having to bother moving arguments around & leaves it a leaf function which is thus able to simply keep the return address live in the ra register throughout, simplifying the code.

| * | MIPS: unify cache initialization codePaul Burton2015-01-29-224/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mips32 & mips64 cache initialization code differs only in that the mips32 code supports reading the cache size from coprocessor 0 registers at runtime. Move the more developed mips32 version to a common arch/mips/lib/cache_init.S & remove the now-redundant mips64 version in order to reduce duplication. The temporary registers used are shuffled slightly in order to work for both mips32 & mips64 builds. The RA register is defined differently to suit mips32 & mips64, but will be removed by a later commit in the series after further cleanup.

| * | MIPS: avoid .set ISA for cache operationsPaul Burton2015-01-29-38/+33
| |/ | | | | | | | | | | | | | | | | | | | | | | As a step towards unifying the cache maintenance code for mips32 & mips64 CPUs, stop using ".set <ISA>" directives in the more developed mips32 version of the code. Instead, when present make use of the GCC builtin for emitting a cache instruction. When not present, simply don't bother with the .set directives since U-boot always builds with -march=mips32 or higher anyway.
