* ARM: OMAP5 / DRA7: Setup L2 Aux Control Register with recommended configurationNishanth Menon2015-03-13-0/+16

* ARM: DRA7 / OMAP5: Add workaround for ARM errata 798870Praveen Rao2015-03-13-0/+7
| | | | | | | | | | | | | | | | | | | This patch enables the workaround for ARM errata 798870 for OMAP5 / DRA7 which says "If back-to-back speculative cache line fills (fill A and fill B) are issued from the L1 data cache of a CPU to the L2 cache, the second request (fill B) is then cancelled, and the second request would have detected a hazard against a recent write or eviction (write B) to the same cache line as fill B then the L2 logic might deadlock." An l2auxctlr accessor implementation for OMAP5 and DRA7 is introduced here as well.

* ARM: DRA7: EMIF: Update SDRAM_REF_CTRL register valueLokesh Vutla2015-02-16-3/+6
| | | | | | | | | | | The value in SDRAM_REF_CTRL controls the delay time between the initial rising edge of DDR_RESETn to rising edge of DDR_CKE (JEDEC specs this as 500us). In order to achieve this, SDRAM_REF_CTRL should be written with a value corresponding to 500us delay before starting DDR initialization sequence, and configure proper value at the end of sequence.

* ARM: OMAP5: DRA7xx: Add support for power rail groupingLubomir Popov2015-01-29-19/+24
| | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>
