| * 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. Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com> [hdegoede@redhat.com: Since we now restore various regs before returning to the FEL BROM code we can drop the sunxi specific #ifdefs in start.S] Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The link register value can be required on some boards (e.g. FEL mode on sunxi) so use a branch instruction to jump to save_boot_params() instead of a branch link. This requires a branch back to save_boot_params_ret so adjust the users to deal with this. For exynos just drop the function since it doesn't do anything.

| * sunxi: video: Do not use CONFIG_SYS_MEM_TOP_HIDE for the framebufferHans de Goede2015-02-16-6/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not use CONFIG_SYS_MEM_TOP_HIDE for the framebuffer, instead override board_get_usable_ram_top to make sure that u-boot is not relocated into the area where we want to use the framebuffer, and patch the devicetree from sunxi_simplefb_setup() to tell the kernel to not touch the framebuffer. This makes u-boot properly see the framebuffer as dram, and initalize the level 2 cache for it, fixing the very slow cfb scrolling problem. As an added bonus this stops us from reserving the framebuffer when simplefb is not used because an older kernel is booted, or hdp is used and no hdmi cable was plugged in, freeing up the memory for kernel use in these cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit a93648d197df48fa46dd55f925ff70468bd81c71 introduced linker generated lists for imagetool which is the base for some host tools (mkimage, dumpimage, et al.). Unfortunately some host tool chains do not support the used type of linker scripts. Therefore this commit broke these host-tools for them, namely FreeBSD and Darwin (OS/X). This commit tries to fix this. In order to have a clean distinction between host and embedded code space we need to introduce our own linker generated list instead of re-using the available linker_lists.h provided functionality. So we copy the implementation used in linux kernel script/mod/file2alias.c which has the very same problem (cause it is a host tool). This code also comes with an abstraction for Mach-O binary format used in Darwin systems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the bootz command to load zImages in case of any new boot scripts. Only the legacy one will still use bootm. Apart form the fact, that this will simplify the image generation process, it saves one copy of the kernel image: Common practice is to generate an uImage with a loading address of 0x8000. This uImage contains a compressed zImage, which will unpack the kernel image to the beginning of the RAM. But because there is already the compressed image the uncompressor first relocates the compressed image to a higher location. The load address is encoded into the uImage which is generated by the distributions and thus cannot be easily changed. By using the bootz command we can load the compressed image to a higher memory address and the decompressor doesn't have to reloacte the image. Signed-off-by: Michael Walle <michael@walle.cc>
