mmc: Split device init to decouple OCR-polling delay
Most of time that MMC driver spends on initializing a device is polling
OCR (operation conditions register). To decouple this polling loop,
device init is split into two parts: The first part fires the OCR query
command, and the second part polls the result. So the caller is now no
longer bound to the OCR-polling delay; he may fire the query, go
somewhere and then come back later for the result.
To use this, call mmc_set_preinit() on any device which needs this.
This can save significant amounts of time on boot (e.g. 200ms) by
hiding the MMC init time behind other init.

usb: hub: Parallelize power-cycling of root-hub ports
Untill now we power-cycle (aka: disable power on a port

Delay of 20ms for Port-power to change multiplies with
number of ports in this case.
So better we parallelize this process:
disable power on all ports, wait for port-power to stabilize
and then re-enable the power subsequently.
Patch b6d7852c increases timeout for enumeration, taking
worst case to be 10 sec.
get_timer() api returns timestamp in milliseconds, which is
what we are checking in the do-while() loop in usb_hub_configure()

part/dev_desc: Add log2 of blocksize to block_dev_desc data struct
log2 of the device block size serves as the shift value used to calculate

It is needed quite often in file systems thus it is pre-calculated and

Bugfix:
Here at this place we need the fat size in sectors not bytes.
This was found during code review when adding support for storage
devices with blocksizes != 512.
disk/gpt: Fix GPT partition handling for blocksize != 512
Disks beyond 2T in size use blocksizes of 4096 bytes. However a lot of
code in u-boot still assumes a 512 byte blocksize.
This patch fixes the handling of GPTs.
Devices that used to have a whole disk FAT filesystem but got then
partitioned will most likely still have a FAT or FAT32 signature
in the first sector as this sector does not get overwritten by
a partitioning tool (otherwise the tool would risk to kill the mbr).
The current partition search algorithm will erronously detects such
a device as a raw FAT device.
Instead of looking for the FAT or FAT32 signatures immediately we
use the same algorithm as used by the Linux kernel and first check
for a valid boot indicator flag on each of the 4 partitions.
If the value of this flag is invalid for the first entry we then
do the raw partition check.
If the flag for any higher partition is wrong we assume the device
is neiter a MBR nor PBR device.
