2019-01-24	a1e0b63 Browse files » MIPS: ath79: add spi and sram bootstrap helpers ... 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.

U-Boot_mod is a popular bootloader for Atheros AR93xx chips, please see https://github.com/pepe2k/u-boot_mod for details. It's reasonable to import some lowlevel AR9331 initialization code from U-Boot_mod. AR9331 (Hornet) 1.1 currently needs an additional reset at 1st boot.
