| * ARM: rpi: save bootargs from VC FDT to vc.bootargsTomaz Solc2019-03-041-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting a Raspberry Pi, it is useful to extract bootargs from the device tree that was created by the VideoCore firmware. These bootargs contain for example settings for the framebuffer that the kernel needs to properly set the video output. This commit extracts the bootargs in the board initialization code and saves them to the vc.bootargs global variable. For example, a bootloader environment can then add the contents of this variable to linux.bootargs.vc, which then gets included into the final bootargs for the kernel using CONFIG_FLEXIBLE_BOOTARGS.

| * ARM: rpi: save fdt that was passed from VideoCoreTomaz Solc2019-03-043-19/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Raspberry Pi, VideoCore firmware creates a device tree that contains information about peripherals that were initialized by VideoCore based on settings in config.txt. Normally this device tree is passed to the Linux kernel via a pointer in the r2 register. A bootloader needs to pass this device tree to the kernel, or some peripherals will not work correctly. Since the VideoCore device tree is not compatible with barebox, we can't just pass it to barebox_arm_entry() as the internal barebox device tree. This commit makes the prebootloader code copy the device tree from VideoCore into a scrap RAM area just above the area reserved for the bootloader. Board initialization code in the bootloader proper then copies it into a file /vc.dtb. The bootloader environment is then free to pass this file to the kernel at boot (e.g. via bootm -o).

| * ARM: rpi: retrieve miniuart clock from firmwareRouven Czerwinski2019-02-051-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | The miniuart uses the core clock as the clock source. This clock is fixed by the firmware to 250Mhz if enable_uart=1 is set in the config.txt file. However a user could still choose to overclock the core frequency, which would result in wrong baudrates computed by barebox. Retrieve the core clock frequency from the firmware to allow all potential firmware configurations to work with barebox.

Barebox is booted as BL33 in EL-1 and expects that a BL2 (i.e. the FSBL) already took care of initializing the RAM. Also for debug_ll, the UART is expected to be already setup correctly. Thus, you have to add the Barebox binary to a boot image as described in "Chapter 11: Boot and Configuration" of "Zynq Ultrascale+ Device Technical Reference Manual".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The socfpga xload images are limited to 64KiB. This doesn't fit if multiple boards are selected. The reason is that we include huge C files and arrays in the early init code which get compiled once for each board. -ffunction-sections is without effect here since all functions have the same name and hence we get the same function multiple times in the same section. To overcome this we surround all function names with a SECT() macro which is used to add a board specific prefix to the section names. This way -ffunction-sections can now do its work and discard unused functions. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

We currently cat the compressed barebox image behind the PBL executable and need some magic to obtain the size of the payload and also have to do tricks to reliably get a pointer to the compressed image. This patch switches over to compile the compressed payload into the PBL image itself which has proven to work for the single PBL case and for the ARM Linux Kernel aswell. The goal is to unify the single PBL and the multi PBL cases together in the future to get an easier startup path for ARM. This patch has been tested on the i.MX53 QSB, i.MX53 Vincell, Beaglebone black (both MLO and 2nd stage) and a Phytec phyFLEX i.MX6 board. SoCFPGA Arria10 has also be changed slightly with this patch. We used to generate a single image (barebox-socfpga-achilles.img) which was used as xload image and full image. We now instead generate two images: barebox-socfpga-achilles-xload.img and barebox-socfpga-achilles.img, the former loaded by the ROM and the latter loaded by the xload image.
