* ARM: 8641/1: treewide: Replace uses of virt_to_phys with __pa_symbolFlorian Fainelli2017-02-281-1/+1
| | | | | | | | | | | All low-level PM/SMP code using virt_to_phys() should actually use __pa_symbol() against kernel symbols. Update code where relevant to move away from virt_to_phys().

* | ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIBLinus Walleij2016-06-031-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | This replaces: - "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can now be selected directly. - "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB is now selectable by everyone, so we need not declare our intent to select it. When ordering the symbols the following rationale was used: if the selects were in alphabetical order, I moved select GPIOLIB to be in alphabetical order, but if the selects were not maintained in alphabetical order, I just replaced "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

| * 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most upstream devs boot STi platform via JTAG which abuses the boot process by setting the PC of secondary cores directly. As a consquence, booting STi platforms via u-boot results in only the primary core being brought up as the code to manage the holding pen is not upstream. This patch adds the necessary code to bring the secondary cores out of the holding pen. It uses the cpu-release-addr DT property to get the address of the holding pen from the bootloader. With this patch booting upstream kernels via u-boot works correctly: [ 0.045456] CPU: Testing write buffer coherency: ok [ 0.045597] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000 [ 0.045734] Setting up static identity map for 0x40209000 - 0x40209098 [ 0.065047] CPU1: thread -1, cpu 1, socket 0, mpidr 80000001 [ 0.065081] Brought up 2 CPUs [ 0.065089] SMP: Total of 2 processors activated (5983.43 BogoMIPS).

| | | | | | | | | | | | This patch removes sti_secondary_start from _INIT section, there are 2 reason for this removal. 1. discarding such a small code does not save much, given the RAM sizes. 2. Having this code discarded, creates corruption issue when we boot smp-kernel with nrcpus=1 or with single cpu node in DT.

* arm: delete __cpuinit/__CPUINIT usage from all ARM usersPaul Gortmaker2013-07-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.
