Hello,
U-Boot patches which add support for Nokia RX-51 (aka N900) is here: http://al.robotfuzz.com/~al/maemo/u-boot/
RX-51 has closed 2nd stage bootloader NOLO which can load kernel image from nand (or usb) to ram and boot it. NOLO also done all HW initializations. These U-Boot patches for RX-51 add support that builded U-Boot binary can be loaded and booted by NOLO. So U-Boot will be 3rd bootloader.
Patches are on top of revision bd2313078114c4b44c4a5ce149af43bcb7fc8854 and working fine. I rebased these patches on top of u-boot git master repository, but booting failed. No output on device. Using git bisect I found that problem appeared at revision
561142af20f1fd7b425d9425730014e656defb91 ARM: implement relocation for ARM V7 (OMAP)
If I defined CONFIG_SYS_ARM_WITHOUT_RELOC U-Boot working and booting fine up to revision a9aa3926295df759306258e5e24cace414f53b67
So problem is that relocation patches broke RX-51 support. Can somebody help me how to rewrite/port rx-51 patches to work with ARM relocation (do not forget that U-Boot is loaded by 2nd bootloader to RAM after HW is initialized by NOLO)? If U-Boot will be working on RX-51 I will prepair patches for upstreaming.
Ali1234 now fixed relocation problem on RX-51. I rebase and fix all patches.
