| * sunxi: Fix sun5i mbus speed when booting old kernelsHans de Goede2015-02-21-0/+9
| | | | | | | | | | | | | | | | | | Older linux-sunxi-3.4 kernels override our PLL6 setting with 300 MHz, halving the mbus frequency, so set it to 300 MHz ourselves and base the mbus divider on that. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* | rpi: add support for Raspberry Pi 2 model BStephen Warren2015-02-21-1/+10
| | | | | | | | | | | | | | | | USB doesn't seem to work yet; the controller detects the on-board Hub/ Ethernet device but can't read the descriptors from it. I haven't investigated yet. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* | bcm2836 SoC support (used in Raspberry Pi 2 model B)Stephen Warren2015-02-21-4/+39
| | | | | | | | | | | | | | | | | | | | | | | | The bcm2835 and bcm2836 are essentially identical, except: - The CPU is an ARM1176 v.s. a quad-core Cortex-A7. - The physical address of many IO controllers has moved. Rather than introducing a whole new bcm2836 value for $(SOC) or $(ARCH), update the existing bcm2835 code to handle the minor differences, and plumb it into the ARMv7 CPU architecture.

| | | | | | | | | | | | | | | | | | | | | | This commit adds $(srctree)/arch/arm/$(machdirs)/include/mach to the headers search path. It allows us to replace "#include <asm/arch/foo.h>" with "#include <mach/foo.h>". As "#include <asm/arch/foo.h>" is still supported, we can modify each file one by one.

This structure did not fit very well in some cases. [1] AT91 AT91 SoC family have been developed across some ARM processor generations. Generally speaking, some IPs are often re-used in the same SoC family (same SoC vendor) even when the main processor is updated. As a result, a SoC-common directory is needed in the upper level. Currently, AT91 source files are placed as follows: arch/arm/cpu/arm920t/at91/* arch/arm/cpu/arm926ejs/at91/* arch/arm/cpu/armv7/at91/* arch/arm/cpu/at91-common/* Once directories are split, the motivation for refactorings across CPU directories is lost. Some files in arm920t/at91/ and arm926ejs/at91/ are so similar that they could be merged. [2] Tegra Tegra is a little bit special case where different CPUs are used for SPL and the main U-boot. To obey the arch/$(ARCH)/cpu/$(CPU)/$(SOC) structure, the source files must be placed across the CPUs, again SoC-common directory is necessary in the upper level. Moreover, there are several families in Tegra: Tegra20, Tegra30, Tegra114, Tegra124. Here again, the tegra-common directory is needed to contain commonly-used files. Tegra directories have been sprinkled in the directory structure. arch/arm/cpu/arm720t/tegra20 arch/arm/cpu/arm720t/tegra30 arch/arm/cpu/arm720t/tegra114 arch/arm/cpu/arm720t/tegra124 arch/arm/cpu/arm720t/tegra-common arch/arm/cpu/armv7/tegra20 arch/arm/cpu/armv7/tegra30 arch/arm/cpu/armv7/tegra114 arch/arm/cpu/armv7/tegra124 arch/arm/cpu/armv7/tegra-common arch/arm/cpu/tegra20-common arch/arm/cpu/tegra30-common arch/arm/cpu/tegra114-common arch/arm/cpu/tegra124-common arch/arm/cpu/tegra-common As you see, splitting SoC code by the CPU is not going well, especially for ARM. Why don't we collect SoC-specific files into a single place? A good example we can follow is Linux's arch/arm/mach-* structure. This item was discussed in the following thread: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/188548/ Looks like I got some positive responses and we are almost ready to start this movement. This commit prepares arch/arm/Makefile for describing machdirs in it. After this commit, we can move SoC directory to arch/arm/mach-$(SOC) in simple steps although some cases such as AT91 and Tegra need more fixes. What we generally have to do is: [1] Move files arch/arm/cpu/$(CPU)/$(SOC)/* to arch/arm/mach-$(SOC)/* [2] Add machine entry into arch/arm/Makefile [3] Remove "obj-y += $(SOC)" from arch/arm/cpu/$(CPU)/Makefile [4] Fix the Kconfig file path in arch/arm/Kconfig [5] Modify MAINTAINERS if necessary Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

| * | sunxi: Support the FEL boot mode in the regular u-boot buildSiarhei Siamashka2015-02-16-10/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So that the CONFIG_SPL_FEL option is not needed anymore. And the regular SPL binary, generated by the default u-boot build, is now also bootable over USB in the FEL mode. The SPL still can boot from the SD card too. A bunch of system registers need to be saved/restored in order to ensure that the IRQ handler still works in the BROM FEL code after getting control back from the SPL. This is done in the sunxi code instead of abusing ifdefs in 'start.S'. The decision whether to load the main u-boot binary from the SD card or return to the FEL code in the BROM is done at runtime.
