[U-Boot] [PATCH v2 1/8] ahci: use ports implemented map instead of num_ports

[U-Boot] [PATCH v2 1/8] ahci: use ports implemented map instead of num_ports

[Rob Herring]

From: Richard Gibbs <richard.gibbs@calxeda.com>

The AHCI driver was incorrectly using the Capabilities register NP (number
of ports) field to determine which ports to activate. This commit changes
it to correctly use the PORTS_IMPL register as a port map.

[U-Boot] [PATCH v2 2/8] ahci: fix unaligned access

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

gcc 4.7 will generate unaligned accesses to local char arrays, so make
them static to avoid that.

[U-Boot] [PATCH v2 6/8] ahci: handle COMINIT received during spin-up

From: Rob Herring <rob.herring@calxeda.com>

Some Intel SSDs can send a COMINIT after the initial COMRESET. This causes
the link to go down and we need to re-initialize the link.

[U-Boot] [PATCH v2 8/8] ahci: convert to use libata functions and definitions

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

libata already has similar functions as implemented in the ahci code.
Refactor the code to use the libata variants and remove the dependency on
ata.h. Convert some defines to use the version from libata.h. Also, remove
some unnecessary memset's of bss data.

This is a step toward hopefully merging ahci.c and dw_ahsata.c which are
essentially the same driver.
