mmc: emmc and hw partitions partition table id bugfix.

2016-01-20T15:19:19+00:00

On bootup the emmc's hw partition is always set to 0 and the partition
table is read from it. When switching to another hw partition the
partition table's id is not updated but instead the old one from
hw partition 0 is used. If there is no partition table on hw partition 0
then the code will terminate and return error even if the desired hw
partition contains a perfectly fine partition table. This fix updates
the partition table struct to correspond to the specified hw partition
before testing if the partition table is valid or not.

Fix GCC format-security errors and convert sprintfs.

2016-01-15T03:11:34+00:00

With format-security errors turned on, GCC picks up the use of sprintf with
a format parameter not being a string literal.

Simple uses of sprintf are also converted to use strcpy.

block: pass block dev not num to read/write/erase()

2016-01-14T02:05:18+00:00

This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.

part:efi: add bootable parameter in gpt command

2015-11-23T16:01:52+00:00

The optional parameter bootable is added in gpt command to set the
partition attribute flag "Legacy BIOS bootable"

This flag is used in extlinux and so in with distro to select
the boot partition where is located the configuration file
(please check out doc/README.distro for details).

With this parameter, U-Boot can be used to create the boot partition
needed for device using distro.

example of use:

setenv partitions "name=u-boot,size=60MiB;name=boot,size=60Mib,bootable;\
                   name=rootfs,size=0"

> gpt write mmc 0 $partitions

> part list mmc 0

Then the distro scripts will search extlinux in partition 2
and not in the first partition.

gpt: part: Definition and declaration of GPT verification functions

2015-11-23T16:01:50+00:00

This commit provides definition and declaration of GPT verification
functions - namely gpt_verify_headers() and gpt_verify_partitions().
The former is used to only check CRC32 of GPT's header and PTEs.
The latter examines each partition entry and compare attributes such as:
name, start offset and size with ones provided at '$partitions' env
variable.
