Hello I'm in for porting bootloader U-Boot and Linux on to ARM-based platform. Now I've reached the point of defining a 'memory map' -- as I understand this is done along with start address of Linux kernel, i.e. what's in $(LINUX)/arch/arm/mach-<board>/Makefile.boot (speaking of 2.6.x kernels). What I don't quite understand is how are the images of bootloader (U-Boot in my case), kernel, initrd (if any) laid out in memory, in what sequences? Does U-Boot copy itself to upper addresses, followed by kernel? As I know the Linux kernel expects parameteres to be received on a specific address in ROM from a bootloader, for ARM platforms these parameters are allocated in ATAG structures -- so how is this address defined, according to chip's datasheet or somehow else? If someone could provide clear example explaining my question - I'd appreciate a lot.
