I know this is a rather long email, but I want to give all the details. Bear with me :-).
I was under the impression that the CFI patch was already included in the f188896c... commit and that I didn't need to apply it. I had tried the git-rebase, but it gave me errors and then wouldn't build. I assumed that the git-rebase step was only required for future patches, so figured I would sort it out later. I should have mentioned that in my last email, I apologize for the miscommunication.
Here's the git-rebase output:

I have applied the CFI patch from the original email using git-am, that seems to work fine. U-boot compiles successfully with these warnings:
david@chiron:~/u-boot$ ./MAKEALL M5275EVB Configuring for M5275EVB board... board.c: In function 'init_baudrate': board.c:179: warning: pointer targets in passing argument 2 of 'getenv_r' differ in signedness board.c:182: warning: pointer targets in passing argument 1 of 'simple_strtoul' differ in signedness m68k_linux.c: In function 'do_bootm_linux': m68k_linux.c:154: warning: implicit declaration of function 'do_reset' m68k-elf-ld: warning: library search path "/lib" is unsafe for cross-compilation m68k-elf-ld: warning: library search path "/usr/lib" is unsafe for cross-compilation m68k-elf-ld: warning: library search path "/usr/local/lib" is unsafe for cross-compilation ./MAKEALL: 265: ppc_8xx-size: not found
I programmed the board (an M5275EVB Rev. B) with the srec using CF Flasher, and U-Boot boots to the prompt.
However, I've run into these problems, and I'm wondering if guys have as well, or if I'm doing something wrong.
1) I can't save environment variables using saveenv. I can change them just fine, and saveenv runs as usual, but on reset, I get a "*** Warning - bad CRC, using default environment "
example:
-> printenv
bootcmd=bootm ffe40000 bootdelay=5
baudrate=19200
ethaddr=00:06:3b:01:41:55
eth1addr=00:0e:0c:bc:e5:60
stdin=serial
stdout=serial
stderr=serial
ethact=FEC0
Environment size: 156/8188 bytes -> setenv ipaddr 192.168.1.101
-> printenv
bootcmd=bootm ffe40000 bootdelay=5
baudrate=19200
ethaddr=00:06:3b:01:41:55
eth1addr=00:0e:0c:bc:e5:60
stdin=serial
stdout=serial
stderr=serial
ethact=FEC0
ipaddr=192.168.1.101
Environment size: 177/8188 bytes -> saveenv

etc.
2) Ethernet does not seem to work. After setting the ipaddr, serverip, and netmask variables, I run tftpboot and don't get anything but checksum errors. The TFTP transfer works fine with the exact same setup (router, ip addresses, etc.) when I use dBug. I've run Wireshark on the ethernet interface and haven't seen a single packet from the board while running the tftpboot command. I've tried pinging the board, seen the packets sent on Wireshark, and got no response.
-> printenv
bootcmd=bootm ffe40000 bootdelay=5
baudrate=19200
ethaddr=00:06:3b:01:41:55
eth1addr=00:0e:0c:bc:e5:60

Anything to clear this up would help. Do either of you have ethernet and saveenv working? Thanks for your help and your patience.
