0472fbfd32 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
the block number to read in file systems when implementing avaiable block
sizes.
It is needed quite often in file systems thus it is pre-calculated and
stored in the block device descriptor.

472d546054 Consolidate bool type
'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.

All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.

Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.

ac1048ae1c drivers/block/systemace - fixed data type in "systemace_read" to match prototype in "block_dev_desc_t"
Currently we have "unsigned long blkcnt" which is fine with
CONFIG_SYS_64BIT_LBA undefined because "lbaint_t" is basically the same
"unsigned long".
If CONFIG_SYS_64BIT_LBA gets defined "lbaint_t" is defined as "unsigned
long long".

Even though not many embedded systems have CONFIG_SYS_64BIT_LBA defined
it's good to have types in function implementation that match exactly
with prototypes.

7cde9f35d6 block: systemace: Added missing "else" in "ace_writew"
System ACE compact flash controller supports either 8-bit (default) or
16-bit data transfers. And in corresponding driver we need to implement
read/write of 16-bit data words properly for both modes of operation.

In existing code if width==8 both branches get executed which may cause
unexpected behavior of SystemAce controller.

Addition of "else" fixes described issue and execution is done as
expected for both (8-bit and 16-bit) data bus widths.

fe1f808ce7 ahci: Expand HDD Logical Block addressability up to 32 bits
Currently, this driver uses a 28bit interface to AHCI, this
limits the number of blocks addressable to 2^28, or the max
disk size to 512(2^28) or about 137GB. This change allows
supporting drives up to about 2TB.

Testing this is a bit difficult. There is test code that
can be inserted into U-Boot that will write test patterns
into certain unused blocks. These patterns can be manually
checked using 'dd' after boot. Another way is to confirm the
original error that exposed this bug is fixed. IOW: see if
AU (Auto Update) will now work on the drive. Also, check
that there are no warning messages from the 'cgpt' utility.

766b16fe18 ahci: Perform SATA flush after disk write.
Writes in u-boot are so rare, and the logic to know when is
the last write and do a flush only there is sufficiently
difficult. Just do a flush after every write. This incurs,
usually, one extra flush when the rare writes do happen.

57847660bb ahci: Adjust SATA timeouts for hard disk (spinup delay & command timeout)
Note: These are timeout values and not delay values, so the event being
timed out will complete whenever it is actually ready, with a
measurement granularity of 1 millisecond, up till the timeout value.
Therefore, there is no effect on SSD booting.

The values were determined by instrumenting the code and measuring the
actual time taken by several different models of HDD for each of the
parameters and then adding 50% more for the spinup value and just
doubling the command timeout value.

SATA controller to explicitly be denoted as physical addresses.

The memory is identity-mapped, so these function calls are a nop, but
they provide good semantic documentation for any maintainers.

The return value of virt_to_phys() is 'unsigned long'.  On machines
where sizeof(unsigned long) != sizeof(pointer), a cast through
(uintptr_t) is needed to appease the compiler due to the potential of
losing the upper 32 bits of the address.

In compilation this scenario, a physical address could be 64-bits, yet
the C pointer environment only allows 32-bit addresses; the constraint
is that pointers cannot address more than 4Gb of memory and if
virt_to_phys() ever returns an out-of-range value for the physical
address, there are issues with emmory mapping which must be solved.
However, since the memory is identify mappeed, there is no problem
introducing the cast: the original pointer will reside in 32-bits, so
the physical address will also be within in 32-bits.

19d1d41e84 ahci: Make the AHCI code find the capacity of disks > 128 GB properly
In the structure returned by the ATA identify device command, there are two
fields which describe the device capacity. One is a 32 bit data type which
reports the number of sectors as a 28 bit LBA, and the other is a 64 bit data
type which is for a 48 bit LBA. If the device doesn't support 48 bit LBAs,
the small value is the only value with the correct size. If it supports more,
if the number of sectors is small enough to fit into 28 bits, both fields
reflect the correct value. If it's too large, the smaller field has 28 bits of
1s, 0xfffffff, and the other field has the correct value.

The AHCI driver is implemented by attaching to the generic SCSI code and
translating on the fly between SCSI binary data structures and AHCI data
structures. It responds to requests to execute specific SCSI commands by
executing the equivalent AHCI commands and then crafting a response which
matches what a SCSI disk would send.

The AHCI driver now considers both fields and chooses the correct one when
implementing both the SCSI READ CAPACITY (10) and READ CAPACITY (16) commands.

e81058c05b ahci: Make sending the SETFEATURES_XFER command optional
This command doesn't really do anything when talking to a SATA device, and
sending it confuses some of them. This change makes sending the command
optional, and defaults to not. The situations where it should be sent are not
the common case.

With the standard SSD in the machine, here are some times with the option
turned off:
1. 8277
2. 8273
3. 8050

And turned on:
1. 8303
2. 8155
3. 8276

Sending that command seems to have no meaningful effect on performance.

This fixes problems with an SSD marked Toshiba NV6424, Taiwan 11159AE P
and TC58NVG5D2FTA10.

It is probably possible to specify 0 as the block count and the driver

read at once to 128 (it should be a power of 2 for the optimal
performance of solid state drives).
