The MPC8308RDB Reference Manual states that no bits in the SPMODE
register are allowed to change while the enable (EN) bit is set.This driver changes the character length bits (LEN) while the enable
(EN) bit is set. Clearing the EN bit while changing the LEN bits makes
the driver work correctly on MPC8308RDB.Signed-off-by: Ira W. Snyder

Support for multiple soft I2C buses.
Multibus I2C support is achieved by defining get_multi_{sda|scl}_pin
functions to switch between multiple "soft" I2C buses.Common definition of I2C_X I2C buses is provided at .

In case the "fdt addr" command wasn't ran yet and any other "fdt"
subcommand was issued, the system crashed due to NULL pointer being
used.This is caused by "fdt addr" command setting up a pointer to the
FDT memory location. Prior issuing "fdt addr", the pointer is NULL
so calling any other subcommands crashed the u-boot.Signed-off-by: Marek Vasut

Using ZLIB compression with UBIFS fails if last data node is not a size of
UBIFS_BLOCK_SIZE (4096 bytes).Easiest way to test this is trying to read a file smaller than 4k:
=> ubifsload 41000000 /etc/fstab
Loading file '/etc/fstab' to addr 0x41000000 with size 704 (0x000002c0)...
UBIFS error (pid 0): read_block: bad data node (block 0, inode 2506)
UBIFS error (pid 0): do_readpage: cannot read page 0 of inode 2506, error -22
Error reading file '/etc/fstab'
/etc/fstab not found!
exit not allowed from main input shell.
=>With this patch:
=> ubifsload 41000000 /etc/fstab

field of the cmd structure, despite the fact that no one ever
*set* that field. When we removed the field, those drivers failed
to compile. Replaced the references with the correct usage of

When setting up the clocks in the sdhci driver, the "spec version"

When I set up Tegra's config files to put the environment into eMMC, I
assumed that CONFIG_ENV_OFFSET was a linearized address relative to the
start of the eMMC device, and spanning HW partitions boot0, boot1,
general* and the user area in order. However, it turns out that the
offset is actually relative to the beginning of the user area. Hence,
the environment block ended up in a different location to expected and
documented.Set CONFIG_SYS_MMC_ENV_PART=2 (boot1) to solve this, and adjust
CONFIG_ENV_OFFSET to be relative to the start of boot1, not the entire
eMMC.Signed-off-by: Stephen Warren

eMMC devices may have hardware-level partitions: 2 boot partitions,
up to 4 general partitions, plus the user area. This change introduces
optional config variable CONFIG_SYS_MMC_ENV_PART to indicate which
partition the environment should be stored in: 0=user, 1=boot0, 2=boot1,
4..7=general0..3. This allows the environment to be kept out of the user
area, which simplifies the management of OS-/user-level (MBR/GPT)
partitions within the user area.Signed-off-by: Stephen Warren

Some eMMC devices contain boot partitions, but do not set the PART_SUPPORT
bit in EXT_CSD_PARTITIONING_SUPPORT. Allow partition selection on such
devices, by enabling partition switching when EXT_CSD_BOOT_MULT is set.Note that the Linux kernel enables access to boot partitions solely based
on the value of EXT_CSD_BOOT_MULT; EXT_CSD_PARTITIONING_SUPPORT only
influences access to "general" partitions.eMMC devices affected by this issue exist on various NVIDIA Tegra
platforms (and presumably many others too), such as Harmony (plug-in eMMC),
Seaboard, Springbank, and Whistler (plug-in eMMC).Signed-off-by: Stephen Warren

Since the type of "ext_csd" was array of char, the following
calculation might fail when the value of ext_csd[EXT_CSD_SEC_CNT]
was minus.capacity = ext_csd[EXT_CSD_SEC_CNT] << 0
| ext_csd[EXT_CSD_SEC_CNT + 1] << 8
| ext_csd[EXT_CSD_SEC_CNT + 2] << 16
| ext_csd[EXT_CSD_SEC_CNT + 3] << 24;So, this patch changes the type of "ext_csd" to array of u8.
