85xx: bugfix for reading maximum TLB size on mpc85xx

2009-06-09T20:58:18+00:00

The MAXSIZE field in the TLB1CFG register is 4 bits, not 8 bits.
This made setup_ddr_tlbs() try to set up a TLB larger than the e500 maximum
(256 MB)
which made u-boot hang in board_init_f() when trying to create a new stack
in RAM.
I have an mpc8540 with one 1GB dimm.

ppc4xx: Fix problem with ECC ordering for PPC4xx NDFC platforms

2009-05-23T10:51:39+00:00

This patch now uses the correct ECC byte order (Smart Media - SMC)
to be used on the 4xx NAND FLASH driver. Without this patch we have
incompatible ECC byte ordering to the Linux kernel NDFC driver.

Please note that we also have to enable CONFIG_MTD_NAND_ECC_SMC in
drivers/mtd/nand/nand_ecc.c for correct operation. This is done with
a seperate patch.

ppc4xx: Move definition for PPC4xx NAND FLASH controller to header

2009-05-23T10:51:39+00:00

This patch moves the definition for the PPC4xx NAND FLASH controller
(NDFC) CONFIG_NAND_NDFC into include/ppc4xx.h. This is needed for the
upcoming fix for the ECC byte ordering of the NDFC driver.

Blackfin: fix timer_init()/timer_reset()

2009-05-19T08:57:33+00:00

The timer_init() function was not using the right csync instruction, nor
was it doing it right after disabling the core timer.

The timer_reset() function would reset the timestamp, but not the actual
timer, so there was a common edge case where get_timer() return a jump of
one timestamp (couple milliseconds) right after resetting.  This caused
many functions to improperly timeout right away.

MIPS: Implement ethernet halt for au1x00

2009-05-16T00:20:03+00:00

Implement ethernet halt() by putting MAC0 in reset.
If we do not do this, we will get memory corruption
when ethernet frames are received during early OS boot.

74xx_7xx: Fix rounding problem in CPU frequency calculation

2009-05-15T20:22:01+00:00

This patch fixes a problem in the CPU frequency calculation. Without it
a 798MHz CPU is displayed as 368.503 MHz. And with it it's 798 MHz.

MPC8260: fixup device tree by property instead of path

2009-05-15T20:03:09+00:00

cpu/mpc8260/cpu.c used to use do_fixup_by_path_u32() to update the
clock frequencies in the device tree, using a CPU path
"/cpus/OF_CPU", with OF_CPU beind defined in the board config file.

However, this does not work when one board config file (here:
MPC8260ADS.h) is intended to be used for several diffrent CPUs and
therefor contains a generic definition like "cpu@0", as the device
trees that will then be loaded will contain specific names like
"PowerPC,8272@0".

We switch to using do_fixup_by_prop_u32() instead, so we can search
for device_type="cpu", as it is done in other architectures, too.

AFEB9260 network fix

2009-05-12T23:17:17+00:00

AFEB9260 uses PA10, PA11 for ETX2 and ETX3.
Also, due to extarnal pull-up on IRQ line, Micrel PHY ID is 1 after reset sequence,
not 0.

Blackfin: avoid get_sclk() with early serial debug

2009-05-06T12:47:27+00:00

When the clock functions were changed to use cached values (and thereby
avoiding expensive math functions), early serial debug broke because the
baud programming is called before external memory is available.
