ARM: Move SYS_CACHELINE_SIZE over to Kconfig

2016-08-26T21:04:46Z

This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all cases we are mirroring the values used by the Linux Kernel here. Also, so long as (and in this case, it is true) we implement flushes in hunks that are no larger than the smallest implementation (and given that we mirror the Linux Kernel, again we are fine) it is OK to align higher. The biggest changes here are that we always use 64 bytes for CPU_V7 even if for example the underlying core is only 32 bytes (this mirrors Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the Linux Kernel) as we do not need multi-platform support (to this degree) and only the Cavium ThunderX 88xx series has a use for such large alignment.

pxa: add support for D- and I- caches

Tested with OHCI and pxafb drivers - no issues found Signed-off-by: Vasily Khoruzhick

pxa: start.S: enable SRAM clock

2016-03-27T13:12:59Z

SRAM is used for early stack, but kernel disables its clock on suspend. Re-enable SRAM clock on startup, otherwise u-boot crashes on resume from suspend. Signed-off-by: Vasily Khoruzhick

arm: pxa: clean-up include file order

Cleaning up order of include files by sorting them alphabetically keeping in mind to leave common.h on top. Signed-off-by: Marcel Ziswiler

arm: pxa: use common timer functions

2015-08-24T18:30:37Z

This patch moves pxa to the common timer functions added in commit 8dfafdd - Introduce common timer functions The (removed) pxa timer code (specifically __udelay()) could deadlock at the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed the 32-bit boundary, the while condition became unconditionally true and locked the processor. Rather than patch the specific pxa issues, simply move everything over to the common code. Signed-off-by: Andrew Ruder Cc: Marek Vasut Cc: Tom Rini

pxa: Fix boot hang by avoiding vector relocation

2015-08-24T18:30:37Z

Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors") pxa does not boot anymore. Add a specific relocate_vectors macro that skips the vector relocation, as the pxa SoC does not provide RAM at the high vectors address (0xFFFF0000), and (0x00000000) maps to ROM. This allows pxa to boot again. Cc: Marek Vasut Signed-off-by: Andrew Ruder

ARM: move -march=* and -mtune= options to arch/arm/Makefile

2015-03-27T15:55:22Z

My main motivations for this commit are: [1] Follow the arch/arm/Makefile style of Linux Kernel [2] Maintain compiler options systematically Currently, we give -march=* and -mtune=* options inconsistently: Only some of the CPUs pass -march=* and -mtune=* options. By collecting such options into the single place arch/arm/Makefile we can tell which options are missing at a glance. [3] Prepare for deprecating arch/*/cpu/*/config.mk Note: This commit just moves the compiler options so as not to change the behavior at all. It does not care about the correctness of the given options. Fox example, "-march=armv5te" might be better than "-march=armv4" for ARM946EJS, but it is beyond the scope this commit. Also, filling the missing -march=* and -tune=* is left to follow-up patches. Signed-off-by: Masahiro Yamada Acked-by: Marek Vasut Acked-by: Stefan Roese

arm: pxa: introducing cpuinfo display for marvell pxa270m

2015-03-05T14:24:10Z

According to table 2-3 on page 87 of Marvell's latest PXA270 Specification Update Rev. I from 2010.04.19 [1] there exists a breed of chips with a new CPU ID for PXA270M A1 stepping which our latest Colibri PXA270 V2.4A modules actually have assembled. This patch helps in correctly identifying those chips upon boot as well which then looks as follows: CPU: Marvell PXA27xM rev.
