* treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada2016-09-23-2/+2
| | | | | | | | | | | Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

* ARM: armv7: move CONFIG_ARMV7_PSCI to KconfigMasahiro Yamada2016-09-07-0/+1
| | | | | | | | | Add ARCH_SUPPORT_PSCI as a non-configurable option that platforms can select. Then, move CONFIG_ARMV7_PSCI, which is automatically enabled if both ARMV7_NONSEC and ARCH_SUPPORT_PSCI are enabled.

| * colibri_imx7: add Colibri iMX7S/iMX7D module supportStefan Agner2016-07-28-0/+7
| | | | | | | | | | | | | | | | | | | | | | This commit adds support for the Toradex Computer on Modules Colibri iMX7S/iMX7D. The two modules/SoC's are very similar hence can be easily supported by one board. The board code detects RAM size at runtime which is one of the differences between the two boards. The board also uses the UART's in DTE mode, hence making use of the new DTE support via serial DM. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>

* | ARM: PSCI: Switch to per-CPU target PC storage in secure data sectionChen-Yu Tsai2016-07-15-5/+8
| | | | | | | | | | | | | | | | | | | | | | Now that we have a secure data section and space to store per-CPU target PC address, switch to it instead of storing the target PC on the stack. Also save clobbered r4-r7 registers on the stack and restore them on return in psci_cpu_on for Tegra, i.MX7, and LS102xA platforms.

* | ARM: PSCI: Split out common stack setup code from psci_arch_initChen-Yu Tsai2016-07-15-16/+0
|/ | | | | | | | | | | | | | | Every platform has the same stack setup code in assembly as part of psci_arch_init. Move this out into a common separate function, psci_stack_setup, for all platforms. This will allow us to move the remaining parts of psci_arch_init into C code, or drop it entirely. Also provide a stub no-op psci_arch_init for platforms that don't need their own specific setup code. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

* imx: imx7d: fix ahb clock mux 1Stefan Agner2016-05-17-1/+1
| | | | | | | | | | | | | | The clock parent of the AHB root clock when using mux option 1 is the SYS PLL 270MHz clock. This is specified in Table 5-11 Clock Root Table of the i.MX 7Dual Applications Processor Reference Manual. While it could be a documentation error, the 270MHz parent is also mentioned in the boot ROM configuration in Table 6-28: The clock is by default at 135MHz due to a POST_PODF value of 1 (=> divider of 2).

* imx: mx7d: isolate resources to domain 0 for A7 corePeng Fan2016-02-21-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current design, if any peripheral was assigned to both A7 and M4, it will receive ipg_stop or ipg_wait when any of the 2 platforms enter low power mode. We will have a risk that, if A7 enter wait, M4 enter stop, peripheral will have chance to get ipg_stop and ipg_wait asserted same time. Also if M4 enters stop mode, A7 will have no chance to access the peripheral. There are 26 peripherals affected by this IC issue: SIM2(sim2/emvsim2) SIM1(sim1/emvsim1) UART1/UART2/UART3/UART4/UART5/UART6/UART7 SAI1/SAI2/SAI3 WDOG1/WDOG2/WDOG3/WDOG4 GPT1/GPT2/GPT3/GPT4 PWM1/PWM2/PWM3/PWM4 ENET1/ENET2 Software Workaround: The solution is to set the peripherals to Domain0 by A core, since A core in Domain0. The peripherals which will be used by M4, will be set to Domain1 by M4. For example, A core set WDOG4 to domain0, but when M4 boots up, M4 will set WDOG4 to domain1, because M4 will use WDOG4. So the peripherals are not shared by them. This way requires the uboot implemented the RDC driver and set the 26 IPs above to domain 0 only. M4 image will set the M4 to domain 1 and set peripheral which it will use to domain 1. This patch enables the CONFIG_IMX_RDC and CONFIG_IMX_BOOTAUX for i.MX7D SABRESD board, and setup the 26 IP resources to domain 0.
