arch/mips/lib/board.c: Fix GCC 4.6 build warning

2011-12-08T20:01:15+00:00

Fix:
board.c: In function 'board_init_r':
board.c:262:8: warning: unused variable 's' [-Wunused-variable]

(raised for configurations without ethernet support like
vct_premium_small)

arch/mips/lib/board.c: make (mostly) checkpatch clean

2011-12-08T20:01:11+00:00

Fix all errors and all warnings except for "externs should be avoided"
which could require more extensive changes.

mips: Use getenv_ulong() in place of getenv(), strtoul

2011-10-23T21:33:19+00:00

This changes the board code to use the new getenv_ulong() function.

consolidate mdelay by providing a common function for all users

2011-10-21T23:16:08+00:00

There are several mdelay() definitions in the driver and
board code. Remove them all and provide a common mdelay()
in lib/time.c.

MIPS: Ingenic XBurst Jz4740 processor support

2011-10-10T13:06:12+00:00

Jz4740 is a multimedia application processor targeting for mobile
devices like e-Dictionary, eBook, portable media player (PMP) and
GPS navigator.  Jz4740 is powered by Ingenic 360 MHz XBurst CPU core
(JzRISC), in which RISC/SIMD/DSP hybrid instruction set architecture
provides high integration, high performance and low power consumption.

JzRISC incorporated in Jz4740 is the advanced and power-efficient
32-bit RISC core, compatible with MIPS32, with 16K I-Cache and 16K
D-Cache, and can operate at speeds up to 400 MHz.

On-chip modules such as LCD controller, embedded audio codec, multi-
channel SAR-ADC, AC97/I2S controller and camera I/F offer a rich
suite of peripherals for multimedia application.  NAND controller
(SLC/MLC), USB (host 1.1 and device 2.0), UART, I2C, SPI, etc. are
also available.

For more info about Ingenic XBurst Jz4740:

This patch introduces XBurst CPU support in U-Boot.  It's compatible
with MIPS32, but requires a bit different cache maintenance, timer
routines, and boot mechanism using USB boot tool, so XBurst support
can go into a separate new home, cpu/xburst/.

net: drop !NET_MULTI code

2011-10-05T20:22:16+00:00

This is long over due.  All but two net drivers have been converted, but
those have now been dropped.

The only thing left to do is actually delete all references to NET_MULTI
and code that is compiled when that is not defined.  So here we scrub the
core code.

image: push default arch values to arch headers

2011-10-05T20:22:15+00:00

This pushes the ugly duplicated arch ifdef lists we maintain in various
image related files out to the arch headers themselves.

console: Implement pre-console buffer

2011-10-05T20:03:09+00:00

Allow redirection of console output prior to console initialisation to a
temporary buffer.

To enable this functionality, the board (or arch) must define:
 - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer
 - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer
 - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes)

The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes
Any earlier characters are silently dropped.

MIPS: mips32: fix wrong loop bound in flush_cache()

2011-09-03T01:43:45+00:00

The issue is found when calling flush_cache() with zero "size" argument.
The bound of loop is miscalculated in this case and flush_cache() enters
a wrong flushing loop.
