| * mx6: ddr: Allow changing REFSEL and REFR fieldsFabio Estevam2016-09-06-4/+2

Looking at the MDREF initialization done via DCD we see that boards do need to initialize these fields differently: $ git grep 0x021b0020 board/ board/bachmann/ot1200/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/ccv/xpress/imximage.cfg:DATA 4 0x021b0020 0x00000800 /* MMDC0_MDREF */ board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x7800 board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6qp.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6dlsabresd.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6slevk/imximage.cfg:DATA 4 0x021b0020 0x00001800 board/freescale/mx6sxsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/freescale/mx6sxsabresd/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/warp/imximage.cfg:DATA 4 0x021b0020 0x00001800 So introduce a mechanism for users to be able to configure REFSEL and REFR fields as needed.

* | treewide: move CONFIG_PHYS_64BIT to KconfigMasahiro Yamada2016-08-05-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to ensure that CONFIG_PHYS_64BIT is configured via Kconfig so that it is always available to the build system. Otherwise we can run into cases where we have inconsistent sizes of certain attributes. Ravi Babu reported offset mismatch of struct dwc3 across files since commit 95ebc253e6d4 ("types.h: move and redefine resource_size_t"). Since the commit, resource_addr_t points to phys_addr_t, whose size is dependent on CONFIG_PHYS_64BIT for ARM architecture. I tried my best to use "select" where possible (for example, ARMv8 architecture) because I think this kind of option is generally user- unconfigurable. However, I see some of PowerPC boards have 36BIT defconfigs as well as 32BIT ones. I moved CONFIG_PHYS_64BIT to the defconfigs for such boards. CONFIG_36BIT is no longer referenced, so all of the defines were removed from CONFIG_SYS_EXTRA_OPTIONS.

* | ARM: Rework and correct barrier definitionsTom Rini2016-08-05-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of testing booting Linux kernels on Rockchip devices, it was discovered by Ziyuan Xu and Sandy Patterson that we had multiple and for some cases incomplete isb definitions. This was causing a failure to boot of the Linux kernel. In order to solve this problem as well as cover any corner cases that we may also have had a number of changes are made in order to consolidate things. First, <asm/barriers.h> now becomes the source of isb/dsb/dmb definitions. This however introduces another complexity. Due to needing to build SPL for 32bit tegra with -march=armv4 we need to borrow the __LINUX_ARM_ARCH__ logic from the Linux Kernel in a more complete form. Move this from arch/arm/lib/Makefile to arch/arm/Makefile and add a comment about it. Now that we can always know what the target CPU is capable off we can get always do the correct thing for the barrier. The final part of this is that need to be consistent everywhere and call isb()/dsb()/dmb() and NOT call ISB/DSB/DMB in some cases and the function names in others.

| * | ARM: PSCI: Remove unused psci_text_end symbolChen-Yu Tsai2016-07-15-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | psci_text_end was used to calculate the PSCI stack address following the secure monitor text. Now that we have an explicit secure stack section, this is no longer used. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
| * | ARM: PSCI: Allocate PSCI stack in secure stack sectionChen-Yu Tsai2016-07-15-11/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have a secure stack section that guarantees usable memory, allocate the PSCI stacks in that section. Also add a diagram detailing how the stacks are placed in memory. Reserved space for the target PC remains unchanged. This should be moved to global variables within a secure data section in the future. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
| * | sunxi: Move remaining PSCI assembly code to CChen-Yu Tsai2016-07-15-54/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch finishes the rewrite of sunxi specific PSCI parts into C code. The assembly-only stack setup code has been factored out into a common function for ARMv7. The GIC setup code can be renamed as psci_arch_init. And we can use an empty stub function for psci_text_end. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
| * | ARM: PSCI: Split out common stack setup code from psci_arch_initChen-Yu Tsai2016-07-15-42/+25
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
