| * | | armv8: semihosting: add a command to load semihosted imagesLinus Walleij2015-03-28-0/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of sprinkling custom code and calls over the Vexpress64 boardfile, create a command that loads images using semihosting just like we would load from flash memory of over the network, using a special command: smhload <image> <address> This will make it possible to remove some custom calls and code and make the boot easier.

| * | | armv8: semihosting: do not inline trap callLinus Walleij2015-03-28-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The semihosting trap call does not like being inlined, probably because that will mean register reordering screwing up the return value in r0, so tag this function "noinline". Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BCM2835 (used on Raspberry Pi) and BCM2836 (used on Raspberry Pi 2) are similar enough. One of the biggest differences is the ARM processor. It is reasonable to collect the source files into a single place, arch/arm/mach-bcm283x/.

| * | | malloc_f: enable SYS_MALLOC_F by default if DM is onMasahiro Yamada2015-03-28-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This option has a bool type, not hex. Fix it and enable it if CONFIG_DM is on because Driver Model always requires malloc memory. Devices are scanned twice, before/after relocation. CONFIG_SYS_MALLOC_F should be enabled to use malloc memory before relocation. As it is board-independent, handle it globally.

* | | | ARM: move -march=* and -mtune= options to arch/arm/MakefileMasahiro Yamada2015-03-27-69/+32

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.

* | ARM: UniPhier: disable L2 cache by lowlevel_init of U-Boot properMasahiro Yamada2015-03-24-17/+5
| | | | | | | | | | | | | | | | | | | | | | | | The L2 cache is used as a temporary SRAM on SPL. Now the secondary CPUs store the necessary code for jumping to Linux on their L1 I-caches. So, the L2 cache can be disabled much earlier, at the very entry of U-Boot proper (lowlevel_init). This makes the boot sequence clearer. Also, as the L1 cache has been disabled by the start.S, enable_caches() does not need to do it again. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

This commit merges the first and the second kicks, so the secondary CPU(s) can directly jump from SPL to Linux. arch/arm/mach-uniphier/smp.S is no longer necessary. Linux boot test passed.

| * | | ARM: tegra: pinmux: account for different drivegroup base registersStephen Warren2015-03-04-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra210 starts its drive group registers at a different offset from the APB MISC register block that other SoCs. Update the code to handle this. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
| * | | ARM: tegra: pinmux: support hsm/schmitt on pinsStephen Warren2015-03-04-4/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | T210 support HSM and Schmitt options in the pinmux register (previous chips placed these options in the drive group register). Update the code to handle this. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
| * | | ARM: tegra: pinmux: partially handle varying register layoutsStephen Warren2015-03-04-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra210 moves some bits around in the pinmux registers. Update the code to handle this. This doesn't attempt to address the issues with the group-to-group varying drive group register layout mentioned earlier. This patch handles the SoC-to-SoC differences in the mux register layout.
