Ben, > I haven't seen the patch that removes the prototypes, but it's > quite possible I looked past it. In a previous e-mail I added a > 'signed-off-by' that John Rigby can add to the patch commit. I > consider this to be a Coldfire patch because it's dependent on > other patches in the series and I have no way of testing it. Here is the one of the two copied from my email box, it will reach u-boot-mailinglist later (not sure how long).

[U-Boot-Users] [PATCH v2] FSL: Fix common EEPROM_data structure definition
by Jon Loeliger 17 Jan '08

17 Jan '08

From: Haiying Wang <Haiying.Wang(a)freescale.com> - Fix EEPROM_data structure definition according to System EEPROM Data Format. - Read MAC addresses from EEPROM to ethXaddr before saving ethXaddr to bd->bi_ethaddr. Signed-off-by: Haiying Wang <Haiying.Wang(a)freescale.com> --- This patch was only tested on MPC8641HPCN board, but it is supposed to work for all NXID boards.

[U-Boot-Users] RM9200 and at49bv642d
by Jonathan Dumaresq 17 Jan '08

17 Jan '08

Hi all, I'm new to u-boot and I want to use it on my new custom design RM9200 board. This is the first time we design a board based to an arm9 cpu. I would like to know if this setup is already done or I should start customizing u-boot to get this work ? My configuration is: 2 x SDRAM MT48LC16M16A2 1 x Flash AT49bv642D I'm not 100% sure, but I think we based our desing on the AT91RM9200EK board for the memory interface. SO I would like to start with something that is the nearest of what I need. I see some U-BOOT source based on the 1.2.0 but I'm not sure from what to start. If someone can point me to the right direction ? Regards Jonathan
