      1 Rebuilding u-boot for Cyrus
      2 
      3 The Cyrus defconfigs are Cyrus_P5020_defconfig and Cyrus_P5040_defconfig.
      4 
      5 They currently disable size optimization in order to avoid a relocation
      6 bug in some versions of GCC. As the output size is a constant, the size
      7 optimization is not currently important.
      8 
      9 Cyrus boots off a microSD card in a slot on the motherboard. This requires
     10 that the u-boot is built for the Pre-Boot Loader on the P5020/P5040.
     11 In order to reflash u-boot, you must download u-boot.pbl, then write it
     12 onto the card. To do that from u-boot:
     13 
     14 > tftp 1000000 u-boot.pbl
     15 > mmc write 1000000 8 672
     16 
     17 If you want to do this via a card reader in linux:
     18 
     19 > dd if=u-boot.pbl of=/dev/sdX bs=512 oseek=8
