Becky Bruce 9973e3c614 Change initdram() return type to phys_size_t This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch only changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>		2008-06-12 08:50:18 +02:00

U-Boot for Artis SBC-A3000
---------------------------

Artis SBC-A3000 has one flash socket that the user uses Intel 28F128J3A (16MB)
or 28F064J3A (8MB) chips.

In board's notation, bank 0 is the one at the address of 0xFF000000.
bank 1 is the one at the address of 0xFF800000

On power-up the processor jumps to the address of 0xFFF00100, the last
megabyte of the bank 0 of flash.

Thus, U-Boot is configured to reside in flash starting at the address of
0xFFF00000.  The environment space is located in flash separately from
U-Boot, at the address of 0xFFFE0000.

There is a National ns83815 10/100M ethernet controller on-board.
