u-boot.git/drivers/block, branch v2014.10-rc2 Unnamed repository; edit this file 'description' to name the repository. ahci: provide sunxi SATA driver using AHCI platform framework 2014-07-31T13:37:22+00:00 Ian Campbell ijc@hellion.org.uk 2014-07-18T19:38:41+00:00 a6e50a88d8d3724fc75f1c6959b80a6c7c69cbad This enables the necessary clocks, in AHB0 and in PLL6_CFG. This is done for sun7i only since I don't have access to any other sunxi platforms with sata included. The PHY setup is derived from the Alwinner releases and Linux, but is mostly undocumented. The Allwinner AHCI controller also requires some magic (and, again, undocumented) DMA initialisation when starting a port. This is added under a suitable ifdef. This option is enabled for Cubieboard, Cubieboard2 and Cubietruck based on contents of Linux DTS files, including SATA power pin config taken from the DTS. All build tested, but runtime tested on Cubieboard2 and Cubietruck only.

AHCI: Increase link timeout to 200ms 2014-07-22T11:44:28+00:00 Ian Campbell ijc@hellion.org.uk 2014-07-18T19:38:39+00:00 e0ddcf93b93eb0bcd99501f90fd62e91c864e114 In 73545f75b66d "ahci: wait longer for link" I increased the timeout to 40ms based on the observed behaviour of a WD disk on a Cubietruck. Since then Karsten Merker and myself have both observed timeouts with HGST disks (Karsten on Cubietruck, me on Cubieboard2). Increasing the timeout to ~175ms fixes this, so go to 200ms for a bit of headroom.

ahci: Fix data abort on multiple scsi resets. 2014-04-02T19:44:40+00:00 Roger Quadros rogerq@ti.com 2014-04-01T14:26:40+00:00 3f62971162370213271dc1e7a396b6b3a6d5b6c6 Commit 2faf5fb82ed6 introduced a regression that causes a data abort when running scsi init followed by scsi reset. There are 2 problems with the original commit 1) ALLOC_CACHE_ALIGN_BUFFER() allocates memory on the stack but is assigned to ataid[port] and used by other functions. 2) The function ata_scsiop_inquiry() tries to free memory which was never allocated on the heap. Fix these problems by using tmpid as a temporary cache aligned buffer. Allocate memory separately for ataid[port] and re-use it if required.

ahci: wait longer for link. 2014-03-10T17:50:31+00:00 Ian Campbell ijc@hellion.org.uk 2014-03-07T01:20:58+00:00 73545f75b66d5bd68076742f082a5b7fdfb5b086 I have observed timeouts on a cubietruck. The increase to 40ms is completely arbitrary and Works For Me(tm). I couldn't find a good reference for how long you are supposed to wait, although googling around it seems like tens of ms rather than single digits is more common. I don't think there is any harm in waiting a bit longer. Signed-off-by: Ian Campbell <ijc@hellion.org.uk>
