freescale: pblimage: refactor CONFIG_SYS_FSL_PBL_{PBI, RCW}

2014-03-12T21:04:49+00:00

Pull out "$(SRCTREE)/" from CONFIG_SYS_FSL_PBL_PBI
and CONFIG_SYS_FSL_PBL_RCW and push it into the top Makefile.

configs: Delete obsolete macro, CONFIG_SYS_GBL_DATA_SIZE

2014-02-19T16:10:05+00:00

CONFIG_SYS_GBL_DATA_SIZE is not used any more.
The size of struct "global_data" is automatically calculated
by asm-offsets. (See lib/asm-offsets.c)

GENERATED_GBL_DATA_SIZE should be used instead of
CONFIG_SYS_GBL_DATA_SIZE.

arm/km: define fdt_high env variable and allow backwards compatibility

2014-02-13T15:18:13+00:00

Add set_fdthigh subcommand to "subbootcmds" (release) so to set "fdt_high"
This is necessary on Kirkwood so that the FDT does not get relocated
above the memory limit that the kernel cannot access
(that is the memory part reserved for the switch).
This was tested on NUSA1, where it is necessary, and on ETER1, where it
doesn't seem to hurt.

We want the scripts to also work with older versions of u-boot, where:
a) set_fdthigh is not defined (will be default env for newer u-boots)
b) the fdt will not be available

For this reason, we use "set_fdthigh" to tell whether we are running
a newer (FDT-aware) u-boot or not.
So if "set_fdthigh" runs successfully or arch != arm we try loading
the fdt; otherwise we proceed normally.

Notice how, contrary to release mode, set_fdthigh will _not_ be part of
subbootcmds for develop and ramfs, but will be executed as part of
"tftpfdt".

Since this is only needed for kirkwood cards, and it prevents the kernel
from booting on QorIQ (though it seemed to work on ETER1), we change
its definition in the default env for powerpc so that the value is only
set on ARM.

arm/km: enable FDT for km_kirwkood

2014-02-13T15:17:54+00:00

This consists of:
a) Defining the addresses, enabling fdtsupport [arm]
b) Defining "cramfsloadfdt"  [arm,powerpc => common]
c) Adding the FDT address to bootm [arm,powerpc => common]
d) Defining "tftpfdt" in ramfs-,develop- [arm,powerpc >= common]

This should work with 3.10 kernels, whether loaded through TFTP
(with rootfs either through NFS or TFTP-ramfs) or from the NAND.

The machid was left unchanged, this should keep compatibility with both
older and newer kernels.

arm/km: add CONFIG_KM_BOARD_EXTRA_ENV to default environment

2014-02-13T15:17:16+00:00

This is needed for board specific additional environment variables.
E.g. the mgcoge3un has this additional "waitforne" variable.

kmp204x: enable support for SPANSION SPI NOR

The new prototype and the final series was moved from Micron to Spansion
to have a better reset sequence that is easier to support.

KM: add the KM_UBI_PART_BOOT_OPTS #define

2014-02-03T16:38:50+00:00

This define can be used if the ubi boot partition (defined for all
Keymile boards with KM_UBI_PARTITION_NAME_BOOT #define to ubi0) needs
some additionnal boot options.

This is the case for the kmp204x boards since u-boot does not support
NAND Flash subpage accesses on this platform, an additionnal argument
that defines the VID offstet must be given to the kernel.

The UBI cmd line option now looks like this "ubi.mtd=ubi0,2048" on this
platform.

kmp204x: I2C deblocking support

2014-02-03T16:38:50+00:00

This patch adds support for using some GPIOs that are connected to the
I2C bus to force the bus lines state and perform some bus deblocking
sequences.

The KM common deblocking algorithm from board/keymile/common/common.c is
used. The GPIO lines used for deblocking the I2C bus are some external
GPIOs provided by the QRIO CPLD:
  - SCL = GPIOA_20
  - SDA = GPIOA_21

The QRIO GPIOs act in an open-drain-like manner, for 0 the line is
driven low and for 1 the GPIO is set as input and the line gets
pulled-up.
