Changes for U-Boot 1.0.0:
======================================================================
+* Patch by Steven Scholz, 10 Oct 2003
+ - Add support for Altera FPGA ACEX1K
+
* Patches by Thomas Lange, 09 Oct 2003:
- fix cmd_ide.c for non ppc boards (read/write functions did not
add ATA base address)
- fix for shannon board
- #ifdef CONFIG_IDE_8xx_DIRECT some otherwise unused code
+ - Endian swap ATA identity for all big endian CPUs, not just PPC
+ - MIPS only: New option CONFIG_MEMSIZE_IN_BYTES for passing memsize
+ args to linux
+ - add support for dbau1x00 board (MIPS32)
* Patch by Sangmoon Kim, 07 Oct 2003:
add support for debris board

- MPC824X Family Member (if CONFIG_MPC824X is defined)
- Define exactly one of
- CONFIG_MPC8240, CONFIG_MPC8245
+ Define exactly one of
+ CONFIG_MPC8240, CONFIG_MPC8245
- 8xx CPU Options: (if using an 8xx cpu)
Define one or more of
- CONFIG_8xx_GCLK_FREQ - if get_gclk_freq() can not work e.g.
- no 32KHz reference PIT/RTC clock
+ CONFIG_8xx_GCLK_FREQ - if get_gclk_freq() cannot work
+ e.g. if there is no 32KHz
+ reference PIT/RTC clock
-- Clock Interface:
+- Linux Kernel Interface:
CONFIG_CLOCKS_IN_MHZ
U-Boot stores all clock information in Hz
"clocks_in_mhz" can be defined so that U-Boot
converts clock data to MHZ before passing it to the
Linux kernel.
-
When CONFIG_CLOCKS_IN_MHZ is defined, a definition of
"clocks_in_mhz=1" is automatically included in the
default environment.
+ CONFIG_MEMSIZE_IN_BYTES [relevant for MIPS only]
+
+ When transfering memsize parameter to linux, some versions
+ expect it to be in bytes, others in MB.
+ Define CONFIG_MEMSIZE_IN_BYTES to make it in bytes.
+
- Console Interface:
Depending on board, define exactly one serial port
(like CONFIG_8xx_CONS_SMC1, CONFIG_8xx_CONS_SMC2,

+----------------------------------------
+DbAu1000 is a development board from AMD containing
+an Alchemy AU1000 with mips32 core.
+
+Limitations & comments
+----------------------
+I assume that you set board to BIG endian!
+Little endian not tested, most probably broken.
+
+I named the board dbau1x00, to allow
+support for all three development boards
+some day ( dbau1000, dbau1100 and dbau1500 ).
+
+I only have a dbau1000, so all testing is limited
+to this board!
+
+The board has two different flash banks, that can
+be selected via dip switch. This makes it possible
+to test new bootloaders without thrashing the YAMON
+boot loader deliviered with board.
+
+Ethernet only supported for mac0.
+
+Pcmcia only supported for slot 0, only 3.3V.
+
+Pcmcia IDE tested with Sandisk Compact Flash and
+IBM microdrive.
+
+###################################
+######## NOTE!!!!!! #########
+###################################
+If you partition a disk on another system (e.g. laptop),
+all bytes will be swapped on 16bit level when using
+PCMCIA!!!!
+
+This is probably due to an error in Au1000 chip.
+
+Solution:
+
+a) Boot via network and partition disk directly from
+dbau1x00. The endian will then be correct.
+
+b) Partition disk on "laptop" and fill it with all files
+you need. Then write a simple program that endian swaps
+whole disk,
+
+Example:
+Original "laptop" byte order:
+B0 B1 B2 B3 B4 B5 B6 B7 B8 B9...
+
+Dbau1000 byte order will then be:
+B1 B0 B3 B2 B5 B4 B7 B6 B9 B8...
