I've copied writelrb and pxa2xx_dram_init from pxa2xx.c
and I think there is a reason why it's done that way and not by
clrsetbits_le32. But if you insist I can replace all calls to writelrb
by clrsetbits.

Because code in pxa2xx.c disable and then re-enable memory.
And u-boot is executed from memory (1st stage bootloder
copied it there).

So tell me how should I specify mac addresses? By EXTRA_ENV_SETTINGS?
