Hmmm, removing this function results in this error:

$ ./MAKEALL titanium
Configuring for titanium - Board: titanium, Options: IMX_CONFIG=board/freescale/titanium/imximage.cfg
make: *** [u-boot] Error 139
arm-linux-gnueabi-size: ./u-boot: File format not recognized
arch/arm/lib/libarm.o: In function `setup_revision_tag':
/home/stefan/git/u-boot/u-boot/arch/arm/lib/bootm.c:215: undefined reference to `get_board_rev'
...

So your patch is not in mainline yet? Is it in the ARM
custodian repo? Then the pending ARM PR will solve this.

I have no strong feelings here, but with Wolfgang preference of the
"<<" notation, I'll change to this:

#define PHYS_SDRAM_SIZE		(512 << 20)

I find this also quite easy to read: "x << 10" is "x KiB" and
"y << 20" is "y MiB". Nothing obscured via some defines.

Best regards,
Stefan
