Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

Freescale MPC8323ERDB Board ----------------------------------------- 1. Memory Map The memory map looks like this: 0x0000_0000 0x03ff_ffff DDR 64M 0x8000_0000 0x8fff_ffff PCI MEM 256M 0x9000_0000 0x9fff_ffff PCI_MMIO 256M 0xe000_0000 0xe00f_ffff IMMR 1M 0xd000_0000 0xd3ff_ffff PCI IO 64M 0xfe00_0000 0xfeff_ffff NOR FLASH (CS0) 16M 2. Compilation Assuming you're using BASH (or similar) as your shell: export CROSS_COMPILE=your-cross-compiler-prefix- make distclean make MPC8323ERDB_config make 3. Downloading and Flashing Images 3.1 Reflash U-Boot Image using U-Boot N.b, have an alternate means of programming the flash available if the new U-Boot doesn't boot. First try a: tftpboot $loadaddr $uboot to make sure that the TFTP load will succeed before an erase goes ahead and wipes out your current firmware. Then do a: run tftpflash which is a shorter version of the manual sequence: tftp $loadaddr u-boot.bin protect off fe000000 +$filesize erase fe000000 +$filesize cp.b $loadaddr fe000000 $filesize To keep your old U-Boot's environment variables, do a: saveenv prior to resetting the board. 3.2 Downloading and Booting Linux Kernel Ensure that all networking-related environment variables are set properly (including ipaddr, serverip, gatewayip (if needed), netmask, ethaddr, eth1addr, rootpath (if using NFS root), fdtfile, and bootfile). Then, do one of the following, depending on whether you want an NFS root or a ramdisk root: run nfsboot or run ramboot 4 Notes The console baudrate for MPC8323ERDB is 115200bps.
