On the at91sam9260ep development board there is an EEPROM
connected to the TWI interface (PA23, PA24 Peripheral A
multiplexing), so we cannot use these pins as ETX2, ETX3.
This patch configures PA10, PA11 pins for ETX2, ETX3
instead of PA23, PA24 pins.

The DIU_DIV register is 8 bit not 5 bit. This prevented large DIV values
so it was not possible to set a slow pixel clock and thus prevented
display on small screens.

This fixes the type pun warnings and makes the code

The formula "counter = (u32) (gd->bus_clk / gd->baudrate) / 32"
can generate the wrong divisor due to integer division truncation.
Round the calculated divisor value by adding 1/2 the baudrate
before dividing by the baudrate.

This patch now moves common.h to the top of the inlcude list. This
is needed for boards with CONFIG_PHYS_64BIT set (e.g. katmai), so that
the phys_size_t/phys_addr_t are defined to the correct size in this

This patch cleans up the 440SPe PCIe register usage. Now only defines

This patch reworks the 440GX interrupt handling so that the common 4xx
code can be used. The 440GX is an exception to all other 4xx variants
by having the cascading interrupt vectors not on UIC0 but on a special
UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references
the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt
handling is simpler without any 440GX special cases.
Also some additional cleanup to cpu/ppc4xx/interrupt.c is done.

This 2nd patch now removes all UIC mask bit definition. They should be
generated from the vectors by using the UIC_MASK() macro from now on.
This way only the vectors need to get defined for new PPC's.
Also only the really used interrupt vectors are now defined. This makes
definitions for new PPC versions easier and less error prone.
Another part of this patch is that the 4xx emac driver got a little
cleanup, since now the usage of the interrupts is clearer.

This patch is the first step to consolidate the UIC related defines in the

steps.

This patch removes some ft_board_setup() functions from some 4xx boards.

This patch completes the preprocessor mneomics for the IBM DDR2 SDRAM
controller registers (MODT and INITPLR) used by the
PowerPC405EX(r). The MMODE and MEMODE registers are unified with their
peer values used for the INITPLR MR and EMR registers,
respectively. Finally, a spelling typo is correct (MANUEL to MANUAL).
With these mnemonics in place, the CFG_SDRAM0_* magic numbers for
Kilauea are replaced by equivalent mnemonics to make it easier to
compare and contrast other 405EX(r)-based boards (e.g. during board
bring-up).
Finally, unified the SDRAM controller register dump routine such that
it can be used across all processor variants that utilize the IBM DDR2
SDRAM controller core. It produces output of the form:
PPC4xx IBM DDR2 Register Dump:
...
SDRAM_MB0CF[40] = 0x00006701
...
which is '<mnemonic>[<DCR #>] = <value>'. The DCR number is included
since it is not uncommon that the DCR values in header files get mixed
up and it helps to validate, at a glance, they match what is printed
in the user manual.
Tested on:
AMCC Kilauea/Haleakala:
- NFS Linux Boot: PASSED
- NAND Linux Boot: PASSED

While the PowerPC 405EX(r) shares in common the AMCC/IBM DDR2 SDRAM
controller core also used in the 440SP, 440SPe, 460EX, and 460GT, in
the 405EX(r), SDRAM_MCSTAT has a different DCR value.
Its present value on the 405EX(r) causes a read back of 0xFFFFFFFF
which causes SDRAM initialization to periodically fail since it can
prematurely indicate SDRAM ready status.

This patch fixes a potentially serious issue related to USB which was
discouvered by Martin Krause <martin.krause@tqs.de> and fixed for
ARM920T. Martin wrote:
Turn off USB to prevent the host controller from writing to the
SDRAM while Linux is booting. This could happen, because the HCCA
(Host Controller Communication Area) lies within the SDRAM and the
host controller writes continously to this area (as busmaster!), for
example to increase the HccaFrameNumber variable, which happens
every 1 ms.
This is a slightly modified version of the patch in order to shutdown
USB when booting on all architectures.
