| * | pbl multiimage: Allow to check image sizesSascha Hauer2019-03-132-0/+11
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PBL images are often constrained in size by limitations exposed by the SoCs SRAM size or partition sizes on the boot device. So far we tried to configure these limits in Kconfig, but with PBL multi images and thus different limitations for the different supported images this no longer works. This patch has another approach for it: During build time make variables containing the relevant sizes for each image are created. These are: PBL_CODE_SIZE_$(symbol) PBL_MEMORY_SIZE_$(symbol) PBL_IMAGE_SIZE_$(symbol) PBL_CODE_SIZE_$(symbol) contains the pure code size of the PBL, it should be smaller than the available SRAM during boot. Normally the PBL's bss segment also needs to be in the initial SRAM, for this case PBL_MEMORY_SIZE_$(symbol) is the relevant variable. PBL_IMAGE_SIZE_$(symbol) contains the full size of the PBL image including the compressed payload (but without any image headers created later by SoC specific image tools). $(symbol) is a placeholder for the start symbol used for this PBL image, thus for the i.MX53 QSB with entry start_imx53_loco PBL_CODE_SIZE_start_imx53_loco will be created. The images/Makefile.* can use these variables directly to check sizes or specify the same variables with a "MAX_" prefix. So when images/Makefile.imx specifies MAX_PBL_CODE_SIZE_start_imx53_loco = 0x10000 then the build system will make sure that the PBL code for the QSB will not get bigger than 64KiB. Also included in this patch are the size restrictions for the i.MX8MQ images as an example how to use this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | 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).
