Fix fallout from autostart revert

2008-08-11T22:06:34+00:00

The autostart revert caused a bit of duplicated code as well as
code that was using images->autostart that needs to get removed so
we can build again.

mips: When booting Linux images, add 'ethaddr' and 'eth1addr' to the environment

2008-07-08T13:31:31+00:00

Add 'ethaddr' and 'eth1addr' to the Linux kernel environment if
they are set in the U-Boot environment.

[MIPS] lib_mips/time.c: Fix CP0 count register usage and timer routines

2008-06-05T13:29:00+00:00

MIPS port has two problems in timer routines. One is now we assume CFG_HZ
equals to CP0 counter frequency, but this is wrong. CFG_HZ has to be 1000
in the U-Boot system.

The other is we don't have a proper time management counter like timestamp
other ARCHs have. We need the 32-bit millisecond clock counter.

This patch introduces timestamp and CYCLES_PER_JIFFY. timestamp is a
32-bit non-overflowing CFG_HZ counter, and CYCLES_PER_JIFFY is the number
of calculated CP0 counter cycles in a CFG_HZ.

STRATEGY:

* Fix improper CFG_HZ value to have 1000

* Use CFG_MIPS_TIMER_FREQ for timer counter frequency, instead.

* timer_init: initialize timestamp and set up the first timer expiration.
  Note that we don't need to initialize CP0 count/compare registers here
  as they have been already zeroed out on the system reset. Leave them as
  they are.

* get_timer: calculate how many timestamps have been passed, then return
  base-relative timestamp. Make sure we can easily count missed timestamps
  regardless of CP0 count/compare value.

* get_ticks: return the current timestamp, that is get_timer(0).

Most parts are from good old Linux v2.6.16 kernel.

v2:
- Remove FIXME comments as they turned out to be trivial.
- Use CP0 compare register as a global variable for expirelo.
- Kill a global variable 'cycles_per_jiffy'. Use #define CYCLES_PER_JIFFY
  instead.

[MIPS] lib_mips/time.c: Fix udelay

2008-06-05T13:29:00+00:00

What we have to do is just to wait for given micro-seconds. No need to
take into account current time, get_timer and CFG_HZ.

[MIPS] lib_mips/time.c: Replace CP0 access functions with existing macros

2008-06-05T13:28:59+00:00

We already have many pre-defined CP0 access macros in .
This patch replaces mips_{compare,count}_set and mips_count_get with
existing macros.

mips: If CONFIG_CMD_SPI is defined, call spi_init()

2008-05-29T15:53:37+00:00

The mips architecture currently does not call 'spi_init()' in the generic
board initialization routine is CONFIG_CMD_SPI is defined.

This patch rectifies that problem.

[MIPS] lib_mips/board.c: Add nand_init

2008-05-29T15:53:37+00:00

This patch adds the standard 'nand_init()' call to the mips generic
'board_init_r()' call, bringing MIPS in line with the other architectures.

Big white-space cleanup.

2008-05-20T22:14:08+00:00

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.
