atmel_mci: Fix data timeout value

2007-08-13T15:35:16+00:00

Calculate the data timeout based on values from the CSD instead of
just using a hardcoded DTOR value. This is a backport of a similar fix
in BSP 2.0, with one additional fix: the DTOCYC value is rounded up
instead of down.

AVR32: Include instead of

2007-08-13T15:22:31+00:00

include/asm-avr32/div64.h was recently moved to include/div64.h, but
cpu/at32ap/interrupts.c wasn't properly updated (an earlier version of
the patch was merged perhaps?)

This patch updates cpu/at32ap/interrupts.c so that the avr32 port
compiles again.

atmel_mci: Use 512 byte blocksize if possible

2007-08-13T14:33:52+00:00

Instead of always using the largest blocksize the card supports, check
if it can support smaller block sizes and use 512 bytes if possible.
Most cards do support this, and other parts of u-boot seem to have
trouble with block sizes different from 512 bytes.

Also enable underrun/overrun protection.

Atmel MCI driver

2007-04-14T14:14:06+00:00

Driver for the Atmel MCI controller (MMC interface) for AT32AP CPUs.

The AT91 ARM-based CPUs use basically the same hardware, so it should
be possible to share this driver, but no effort has been made so far.

Hardware documentation can be found in the AT32AP7000 data sheet,
which can be downloaded from

AVR32: Add clk and gpio infrastructure for mmci

2007-04-14T14:14:06+00:00

Implement functions for configuring the mmci pins, as well as
functions for getting the clock rate of the mmci controller.

AVR32: Add clk and gpio infrastructure for macb0 and macb1

2007-04-14T14:14:06+00:00

Implement functions for configuring the macb0 and macb1 pins, as
well as functions for getting the clock rate of the various
busses the macb ethernet controllers are connected to.

AVR32: Relocate u-boot to SDRAM

2007-04-14T13:20:27+00:00

Relocate the u-boot image into SDRAM like everyone else does. This
means that we can handle much larger .data and .bss than we used to.

AVR32: Resource management rewrite

2007-04-14T13:20:27+00:00

Rewrite the resource management code (i.e. I/O memory, clock gating,
gpio) so it doesn't depend on any global state. This is necessary
because this code is heavily used before relocation to RAM, so we
can't write to any global variables.

As an added bonus, this makes u-boot's memory footprint a bit smaller,
although some functionality has been left out; all clocks are enabled
all the time, and there's no checking for gpio line conflicts.

AVR32: Split start_u_boot into board_init_f and board_init_r

2007-04-14T13:20:20+00:00

Split the avr32 initialization code into a function to run before
relocation, board_init_f and a function to run after relocation,
board_init_r. For now, board_init_f simply calls board_init_r
at the end.
