SPDX-License-Identifier: GPL-2.0 - -BMIPS DeviceTree Booting ------------------------- - - Some bootloaders only support a single entry point, at the start of the - kernel image. Other bootloaders will jump to the ELF start address. - Both schemes are supported; CONFIG_BOOT_RAW=y and CONFIG_NO_EXCEPT_FILL=y, - so the first instruction immediately jumps to kernel_entry(). - - Similar to the arch/arm case (b), a DT-aware bootloader is expected to - set up the following registers: - - a0 : 0 - - a1 : 0xffffffff - - a2 : Physical pointer to the device tree block (defined in chapter - II) in RAM. The device tree can be located anywhere in the first - 512MB of the physical address space (0x00000000 - 0x1fffffff), - aligned on a 64 bit boundary. - - Legacy bootloaders do not use this convention, and they do not pass in a - DT block. In this case, Linux will look for a builtin DTB, selected via - CONFIG_DT_*. - - This convention is defined for 32-bit systems only, as there are not - currently any 64-bit BMIPS implementations. |
