2015-06-12ahci: support LBA48 data reads for 2+TB drivesMark Langsdorf
Enable full 48-bit LBA48 data reads by passing the upper word of the LBA block pointer in bytes 9 and 10 of the FIS. This allows uboot to load data from any arbitrary sector on a drive with 2 or more TB of available data connected to an AHCI controller.

2015-04-07ahci: Fix a wrong parameter passTang Yuantian
In stead of user_buffer_size, transfer_size should be used to pass to ahci_device_data_io(). transfer_size is the length that we want the low level function to transfer each time. If we use user_buffer_size which is the totally data length as parameter, low level function will actually create many SGs to transfer as many data as possible each time. That will produce many redundant data transfer. Signed-off-by: Tang Yuantian <Yuantian.Tang@freescale.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2015-01-23x86: ahci: Make sure interface is not busy after enabling the portBin Meng
Each time U-Boot boots on Intel Crown Bay board, the displayed hard drive information is wrong. It could be either wrong capacity or just a 'Capacity: not available' message. After enabling the debug switch, we can see the scsi inquiry command did not execute successfully. However, doing a 'scsi scan' in the U-Boot shell does not expose this issue. SCSI: Target spinup took 0 ms. SATA link 1 timeout. AHCI 0001.0100 32 slots 2 ports 3 Gbps 0x3 impl SATA mode flags: ncq stag pm led clo only pmp pio slum part ccc apst scanning bus for devices... ahci_device_data_io: 0 byte transferred. <--- scsi inquiry fails ahci_device_data_io: 512 byte transferred. ahci_device_data_io: 512 byte transferred. ahci_device_data_io: 512 byte transferred.

So uninitialized contents on the stack were passed to dev_print() to display those wrong information. The symptom were observed on two hard drives (one is Seagate, the other one is Western Digital). The fix is to make sure the AHCI interface is not busy by checking the error and status information from task file register after enabling the port in ahci_port_start() before proceeding other operations like scsi_scan().

2014-07-31ahci: provide sunxi SATA driver using AHCI platform frameworkIan Campbell
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.

2014-04-02ahci: Fix data abort on multiple scsi resets.Roger Quadros
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.
