In this series we prepare the RaspberryPi source code to be able to build one binary for RPi[3,4] and one for RPi[1,2]. To achieve this we need to set the IO base address on runtime. Apart from that, for arm64 we also need to set memory region correctly.
This patches fix this stuff. With this we could create one binary for each armv7 and armv8 based RPis. There is still some work to do to create a unified config, which will be done in a later patch series.
Changes in v4: - use gcc attribute instead of random assignment - read IO base from device-tree - call rpi_update_mem_map only for ARM64 - get rid of struct pdata
Changes in v3: - fix armv7 build
Changes in v2: - push fw_dtb_pointer into the .data section - fix register access in reset_cpu() - rename BCM2838 to BCM2711 in the correct patch - push rpi_bcm283x_base into the .data section - Move mem_map out of assembly file - push mem_map into the .data section - update the members of mem_map instead of the pointer
Matthias Brugger (4): rpi: push fw_dtb_pointer in the .data section ARM: bcm283x: Move BCM283x_BASE to a global variable ARM: bcm283x: Set rpi_bcm283x_base at run-time ARM: bcm283x: Set memory map at run-time
