 ; ROMSTART entry specifies the start address, here 0x80100000
 ; IMPORTANT: do *not* add 4k page to ROMSTART - we need the TOC!

 ; ROMOFFSET adds an offset to RAMIMAGE for flash load addresses,
 ; here 0x1F470400

 ; if you want to debug the tiny startup sequence, that is running
 ; in physical address mode, you have to relocate code symbols to physical:

 ;sYmbol.RELOC P:(0x80200000-0x80200000)
 ;Go KernelStart /Onchip   ; onchip because of cache switches

 ; after switching to virtual address; re-relocate symbols

 ;sYmbol.RELOC P:0x00000000

 ; use onchip because we switch on MMU
 ;Go ARMInit /Onchip
 Go OEMInit /Onchip
