Dear Heiko Schocher,
In message 4CCFAFE4.3000600@denx.de you wrote:
- preloader copies first page of nand (nand_spl code) to 0xbb000000 (some cpu internal mem) and jumps to this address
- nand_spl does lowlevelinit, relocate itself to TEXT_BASE (nand_spl code)
Why is this relocation needed? I understand that this 0xbb000000 address is determined by the given hardware ans as such always fix?
But as codesize changes (and with it relocation address) this is not a perfect solution.
Indeed. CONFIG_SYS_NAND_U_BOOT_SIZE should be dropped, and the avtual value should be derived from the actual U-Boot image building process.
Best regards,
Wolfgang Denk
