* ARM: qcom: Cleanup/Remove unnecessary board fileAndy Gross2016-08-232-32/+0
| | | | | | | | This patch removes the unnecessary board file. The generic machine definition is sufficient for the Qualcomm platforms. Signed-off-by: Andy Gross <andy.gross@linaro.org> Reviewed-by: Stephen Boyd <sboyd@codeaurora.org>

* ARM: use "depends on" for SoC configs instead of "if" after promptMasahiro Yamada2015-12-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many ARM sub-architectures use prompts followed by "if" conditional, but it is wrong. Please notice the difference between config ARCH_FOO bool "Foo SoCs" if ARCH_MULTI_V7 and config ARCH_FOO bool "Foo SoCs" depends on ARCH_MULTI_V7 These two are *not* equivalent! In the former statement, it is not ARCH_FOO, but its prompt that depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO is selected by another, but ARCH_MULTI_V7 is still disabled. As it is not unmet dependency, Kconfig never warns. This is probably not what you want. The former should be used only when you need to do so, and you really understand what you are doing. (In most cases, it should be wrong!) For enabling/disabling sub-architectures, the latter is always correct. As a good side effect, this commit fixes some entries over 80 columns (mach-imx, mach-integrator, mach-mbevu).

Also included are some cleanups where the platform maintainers hadn't separated cleanups from new developent in separate branches. Some of the larger things worth pointing out: - A large set of changes from Alexandre Belloni and Nicolas Ferre preparing at91 platforms for multiplatform and cleaning up quite a bit in the process. - Removal of CSR's "Marco" SoC platform that never made it out to the market. We love seeing these since it means the vendor published support before product was out, which is exactly what we want! New platforms this release are: - Conexant Digicolor (CX92755 SoC) - Hisilicon HiP01 SoC - CSR/sirf Atlas7 SoC - ST STiH418 SoC - Common code changes for Nvidia Tegra132 (64-bit SoC) We're seeing more and more platforms having a harder time labelling changes as cleanups vs new development -- which is a good sign that we've come quite far on the cleanup effort.

| | | | | | | | | | | | | | | | | | | | | | | | | | When an error occurs during an scm call the error returned is remapped so we lose the original error code.

| | | | | | | | | | | | | | | | | | | | | | | | scm_call flushes the entire cache before calling into the secure world. This is both a performance penalty as well as insufficient on SMP systems where the CPUs possess a write-back L1 cache. Flush only the command and response buffers instead, moving the responsibility of flushing any other cached buffer (being passed to the secure world) to callers.

| | | | | | | | | | | | | | | | | | | | | | | | | | The cache invalidation in scm_call() correctly rounds down the start address to invalidate the beginning of the cacheline but doesn't properly round up the 'end' address to make it aligned. The last chunk of the buffer won't be invalidated when 'end' is not cacheline size aligned so make sure to invalidate the last few bytes in such situations. It also doesn't do anything about outer caches so make sure to invalidate and flush those as well. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Kumar Gala <galak@codeaurora.org>
