b6458d38d6 ide: Correct function signatures for ide_read/write()
The prototypes in the header were changed by commit 4ac8f8e0 but the
functions no longer match. Correct this.

It seems odd that block devices take an lbaint_t for the block count, but
an unsigned long for the blknr. Surely we should promote blknr to lbaint_t
also?

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.

64738e8ae8 ahci: Use virt_to_phys() to denote physical addresses for DMA
Update the assignment of various physical memory buffers used by the
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.

This change allows the config file to define a list of PCI vendor

the first device it finds.

which configuration U-Boot was built for. Some U-Boot binaries run on
multiple boards, and hence this information may not uniquley describe
the HW that U-Boot is actually running on. Another patch introduces
environment variable board_name to represent that. In order to avoid
scripts having to check $board_name, use it if set, and then fall back
to using $board, make CONFIG_ENV_VARS_UBOOT_CONFIG also set a default
value for board_name, so that variable is always available.

and transparently handle either file-system. This scheme could easily be
extended to other filesystem types; I only didn't do it for zfs because
I don't have any filesystems of that type to test with.

Replace the implementation of {fat,ext[24]}{ls,load} with this new code
too.

03e2ecf6b8 fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}
This makes the FAT and ext4 filesystem implementations build if
CONFIG_FS_{FAT,EXT4} are defined, rather than basing the build on
whether CONFIG_CMD_{FAT,EXT*} are defined. This will allow the
filesystems to be built separately from the filesystem-specific commands
that use them. This paves the way for the creation of filesystem-generic
commands that used the filesystems, without requiring the filesystem-
specific commands.

Minor documentation changes are made for this change.

The new config options are automatically selected by the old config
options to retain backwards-compatibility.

672ee2110c fs: delete unused Makefile
fs/Makefile is unused. The top-level Makefile sets LIBS-y += fs/xxx and
hence causes make to directly descend two directory levels into each
individual filesystem, and it never descends into fs/ itself.

So, delete this useless file.
