* / pbl multiimage: Allow to check image sizesSascha Hauer2019-03-131-0/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | MIPS: ath79: add spi and sram bootstrap helpersOleksij Rempel2019-01-247-0/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least some ath79 SoC have build in 32K RAM. It allow us to use lowlevel portion of barebox to bootstrap the system by using JTAG debugger (For example OpenOCD). Since ath79 has no reliable way to stop the CPU execution before reading SPI Flash, this can cause different issues. To avoid it, we need to flash a execution trap with software debug breakpoint to the flash. The workflow should be as follow: - After power on or reset the CPU will start execution of SPI flash. As soon as software debug breakpoint is executed, CPU will halt and notify OpenOCD about breakpoint event. - OpenOCD will load reduced barebox to SRAM and execute it. This part will do all needed low level initialization - PLL, RAM and trigger second breakpoint event. - OpenOCD will load full barebox version to the main RAM and start execution. It can be used for bring-up, so no regular flashing is needed. Signed-off-by: Oleksij Rempel <linux@rempel-privat.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | -Wmissing-prototypes is a useful warning, so add it to the build. With this we can detect conflicting function prototypes.
