PATCH v2 1/8 ahci: use ports implemented map instead of num_ports

From: Richard Gibbs <[email protected]>

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.

PATCH v2 6/8 ahci: handle COMINIT received during spin-up

In reply to Rob Herring

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.

PATCH v2 8/8 ahci: convert to use libata functions and definitions

In reply to Rob Herring

From: Rob Herring <[email protected]>

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.

PATCH v2 1/8 ahci: use ports implemented map instead of num_ports

In reply to Rob Herring
Quoted 8 lines · Rob Herring

From: Richard Gibbs <[email protected]>

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.

Applied to u-boot/master along with the rest of the series, thanks!
