| * sunxi: Machine id hack to prevent loading buggy sunxi-3.4 kernelsSiarhei Siamashka2015-02-21-6/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now U-Boot supports the CONFIG_OLD_SUNXI_KERNEL_COMPAT option, which makes it go out of its way in limiting the selection of PLL clock frequencies and PMIC voltages in order not to upset outdated buggy sunxi-3.4 kernel releases. And if the CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set, then booting such old kernels exhibits various failures at runtime. This is very user unfriendly, and there were already several incidents when people wasted their time being hit by these runtime failures and trying to debug them. The right solution is not to add hacks and workarounds to the mainline U-Boot, but to fix these bugs in the sunxi-3.4 kernel. And in fact, the updated sunxi-3.4 kernels already exist. Still we need to follow the 'Principle of Least Surprise' and U-Boot needs to ensure that the old buggy kernels are not getting happily booted when the CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set. And this patch addresses this particular issue. This patch makes U-Boot store the 'compatibility revision' number in the top 4 bits of the machine id and pass it to the kernel. The old buggy kernels will fail to load with a very much googlable error message on the serial console (the "r1 = 0x100010bb" part of it): "Error: unrecognized/unsupported machine ID (r1 = 0x100010bb)" This error message can be documented in the linux-sunxi wiki with proper explanations about how to resolve this situation and where to get the necessary bugfixes for the sunxi-3.4 kernel. The fixed sunxi-3.4 kernels implement a revision compatibility check and clear the top 4 bits of the machine id if everything is alright. By accepting the machine id with the bits 31:28 set to 1, the sunxi-3.4 kernel effectively certifies that it has the PLL5 clock speed and AXP209 DCDC3 voltage fixes applied. It is still possible to set the CONFIG_OLD_SUNXI_KERNEL_COMPAT option in U-Boot if the user desires to use an outdated unpatched sunxi-3.4 kernel.

| * sunxi: Set the /chosen/stdout-path fdt property for sunxi boardsHans de Goede2015-02-21-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While discussing with some people how to get the Linux kernel to do the right thing wrt sending output to both the serial console and the hdmi out / lcd screen when booting on ARM devices, Grant Likely pointed out that there already is a solution for this. All we need to do is set the /chosen/stdout-path fdt property, and if no console= arguments were specified on the kernel commandline the kernel will honor this and add this device as a console (next to the primary video output on hdmi). And u-boot already has support for setting this, all we need to do is define OF_STDOUT_PATH and then everything will just work ootb, without people needing to meddle with adding console= arguments in extlinux.conf .

* | serial: Support an early UART for debuggingSimon Glass2015-02-19-0/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org>

| * | sunxi: video: Do not use CONFIG_SYS_MEM_TOP_HIDE for the framebufferHans de Goede2015-02-16-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | lsxl: switch from bootm to bootz for boot commandsMichael Walle2015-02-12-13/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dtb was loaded at a memory address after the initial ramdisk. Thus a large ramdisk would overwrite the dtb. Move it to "ramdisk_start - 64k". 64k should be enough for the device tree blob. Also the kernel documentation arm/Booting suggests to put the dtb before the initial ramdisk.

| |/ | | | | | | | | | | | | | | | | | | The load addresses for the bootcmd_legacy script were taken from the original bootloader from Buffalo. But newer kernels are too big and the uncompressing will overwrite parts of the initial ramdisk. Therefore, we switch to the load addresses which are also used by the other boot script.
