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.

The existing code waits a whole second for the AHCI controller to reset.
Instead, let's poll the status register to see if the reset has
succeeded and return earlier if possible. This brings down the time for
AHCI probing from 1s to 20ms.

With an Intel AHCI controller, the driver does not operate properly
if the requested amount of blocks to read exceeds 255.
It is probably possible to specify 0 as the block count and the driver
will read 256 blocks, but it was decided to limit the number of blocks
read at once to 128 (it should be a power of 2 for the optimal
performance of solid state drives).

- block_dev_desc_t says that block_(read|write) take lbaint_t for blkcnt
not ulong.
- We also move the extern of sata_dev_desc into <sata.h>
- Remove now duplicate declarations from driver-specific headers.

We set sata_curr_device to 0 right after returning from init_sata(), so there's
no point in setting it to the last scanned driver at this point.
Note: there are more duplicities with cmd_sata, but those might be required,
as the code seems to reset the entire controller on every scan, ignoring the
requested port number.

- Supports one/two/four independent Serial ATA channels
- Supports Serial ATA Generation 2 transfer rate of 3.0 Gbit/s
- Supports LBA28 and LBA48

Faraday's ftide020_s is an IDE-AHB controller for SoC design.
This patch add the u-boot driver (PIO) of ftide020 ATA (IDE) driver.
IDE commands include read, info, and other functions has been implemented.
Because this IDE controller support AHB interface only which is differ
from other most IDE controller supports PCI interface. Some registers
access is required during CMD/DATA I/O. Hence a configuration
"CONFIG_IDE_AHB" is required to be defined according to the feature in
cmd_ide.c.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

On the MPC85xx platform if we have SATA its connected on SERDES.
Determing if SATA is enabled via sata_initialize should not be board
specific and thus we move it out of the MPC8536DS board code.
Additionally, now that we have is_serdes_configured() we can determine
if the given SATA port is enabled and error out if its not in the
driver.
