This patch re-formats the arm920t s3c24x0 driver files, excluding the nand
driver, in preparation for changes to add support for the Embest SBC2440-II Board.
The changes are as follows:
- re-indent the code using Lindent
- make sure register layouts are defined using a C struct
- replace the upper-case typedef'ed C struct names with lower case
non-typedef'ed ones
- make sure registers are accessed using the proper accessor functions
- run checkpatch.pl and fix any error reports
It assumes the following patch has been applied first:
- [U-Boot][PATCH-ARM] CONFIG_SYS_HZ fix for ARM902T S3C24X0 Boards, 05/09/2009
- patches 1/4 and 2/4 of this series

TI OMAP3 Use arm init sequence to initialize i2c
This changes fixes an early i2c error.
It appears that I2C is working because once a read or write
error is detected, the omap24xx_i2c driver calls i2c_init
inside its error handling check.
While it is ok to attempt error handling this way, the boards
must not depend on this side effect to initialize it's i2c.
Instead of explicitly calling i2c_init for every board, use
the generic arm initialization in lib_arm/board.c. By defining

Also another flag to enable NAND functions was being

This patch does the following
1) Enables the NAND driver which is now available.
2) Enables the 'CONFIG_MTD_DEVICE' as without this the
compilation will fail
3) We now have a safe place to store environment and defines
an offset where this can be stored. This offset value is such that it is after
the location where U-Boot is flashed using TI flash utilities.
4) Enables Bootdelay
5) Increases malloc() arena size. Manufacturers are coming out with
NAND with large blocks sizes of upto 1 MiB. It has been noticed that
as the block size of the NAND used is increased, if this particular
value is not increased, the NAND driver will output out of memory

Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.
This feature is useful when your board uses different mii buses for different
phys and all (or a part) of these buses are implemented via bit-banging mode.
The driver requires that the following macros should be defined into the board
configuration file:
CONFIG_BITBANGMII - Enable the miiphybb driver
CONFIG_BITBANGMII_MULTI - Enable the multi bus support
If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
to define at least the following macros:
MII_INIT - Generic code to enable the MII bus (optional)
MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
MDIO_ACTIVE - Activate the MDIO pin as out pin
MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
MDIO_READ - Read the MDIO pin
MDIO(v) - Write v on the MDIO pin
MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
MDC(v) - Write v on the MDC pin
The previous macros make the driver compatible with the previous version
(that didn't support the multi-bus).
When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
the bb_miiphy_buses[] array with a record for each required bus and declare
the bb_miiphy_buses_num variable with the number of mii buses.
The record (struct bb_miiphy_bus) has the following fields/callbacks (see
miiphy.h for details):
char name[] - The symbolic name that must be equal to the MII bus
registered name
int (*init)() - Initialization function called at startup time (just
before the Ethernet initialization)
int (*mdio_active)() - Activate the MDIO pin as output
int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
int (*set_mdio)() - Write the MDIO pin
int (*get_mdio)() - Read the MDIO pin
int (*set_mdc)() - Write the MDC pin
int (*delay)() - Delay function
void *priv - Private data used by board specific code
NULL is an absolute value and should not be relocated.
After this correction code like:
void weak_fun(void) __attribute__((weak));
printf("weak_fun:%p\n", weak_fun);
will still print null after relocation.

This is a temporary workaround. The end goal is to add support to

MPC8536E can support booting from NAND flash which uses the
image u-boot-nand.bin. This image contains two parts: a 4K
NAND loader and a main U-Boot image. The former is appended
to the latter to produce u-boot-nand.bin. The 4K NAND loader
includes the corresponding nand_spl directory, along with the
code twisted by CONFIG_NAND_SPL. The main U-Boot image just
like a general U-Boot image except the parts that included by
CONFIG_SYS_RAMBOOT.
When power on, eLBC will automatically load from bank 0 the
4K NAND loader into the FCM buffer RAM where CPU can execute
the boot code directly. In the first stage, the NAND loader
copies itself to RAM or L2SRAM to free up the FCM buffer RAM,
then loads the main image from NAND flash to RAM or L2SRAM
and boot from it.
This patch implements the NAND loader to load the main image
into L2SRAM, so the main image can configure the RAM by using
SPD EEPROM. In the first stage, the NAND loader copies itself
to the second to last 4K address space, and uses the last 4K
address space as the initial RAM for stack.
Obviously, the size of L2SRAM shouldn't be less than the size
of the image used. If so, the workaround is to generate another
image that includes the code to configure the RAM by SPD and
load it to L2SRAM first, then relocate the main image to RAM
to boot up.

sbc8548: reclaim wasted sector in boot flash
By nature of being based off the MPC8548CDS board, this
board inherited an ENV_SIZE setting of 256k. But since
it has a smaller flash device (8MB soldered on), it has
a native sector size of 128k, and hence the ENV_SIZE was
causing 2 sectors to be used for the environment.
By removing the unused sector, we can push TEXT_BASE up
closer to the end of address space and reclaim that
sector for any other application. This also fixes the
mismatch between TEXT_BASE and MONITOR_LEN reported by
Kumar earlier.
Since this board also supports the ability to boot off
the 64MB SODIMM flash, this change is forward looking
with that in mind; i.e. the settings for MONITOR_LEN
and ENV_SIZE will work when the 512k sectors of the
SODIMM flash are used for alternate boot in the future.

ppc4xx: Convert PPC4xx SDRAM defines from lower case to upper case
The latest PPC4xx register cleanup patch missed some SDRAM defines.
This patch now changes lower case UIC defines to upper case. Also
some names are changed to match the naming in the IBM/AMCC users
manuals (e.g. mem_mcopt1 -> SDRAM0_CFG).
__i2c_read always ends with a STOP condition thereby releasing
the bus. It is cleaner to do the STOP magic in i2c_read(), like
i2c_write() does. This may also help future multimaster systems which
wants to hold on to the bus until all transactions are finished.
fsl_i2c: Impl. AN2919, rev 5 to calculate FDR/DFSR
The latest AN2919 has changed the way FDR/DFSR should be calculated.
Update the driver according to spec. However, Condition 2
is not accounted for as it is not clear how to do so.
