AndU-Boot reserve memory from 0x800000 with 0x400000 size in orderto make it invisible for kernel.Please use rockchip tool "mkkrnlimg" to pack firmware binary, example:./scripts/mkkrnlimg mcu-os1.bin mcu-os1.imgChange-Id: I127d5d9f460ec0c1812a76fb4c3702e82f21c9a6Signed-off-by: Joseph Chen <chenjh@rock-chips.com> List of files: /rk3399_rockchip-uboot/drivers/cpu/Kconfig Thu, 21 Mar 2019 10:22:13 +0000 Joseph Chen <chenjh@rock-chips.com> http://opengrok.muzhidianzi.cn:8080/history/rk3399_rockchip-uboot/drivers/cpu/Kconfig#11f4dc1583c387fbb46d473c942c4bcfe5af303e dm: Implement a CPU uclassIt is useful to be able to keep track of the available CPUs in a multi-CPUsystem. This uclass is mostly intended for use with SMP systems.The uclass provides methods for getting basic information about each CPU.Signed-off-by: Simon Glass <sjg@chromium.org>Reviewed-by: Bin Meng <bmeng.cn@gmail.com> List of files: /rk3399_rockchip-uboot/drivers/cpu/Kconfig Wed, 29 Apr 2015 02:25:09 +0000 Simon Glass <sjg@chromium.org>
