| * block: ahci: Don't enable port interruptsStefan Roese2015-07-10-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the initialization of the AHCI controller to not enable the default interrupts (DEF_PORT_IRQ). As interrupts are not used in U-Boot in general, this should not break the common AHCI driver operation. This change is needed to support the Marvell Armada 38x AHCI controller. With interrupts enabled, this results in timeouts in ahci_device_data_io(). Not enabling these interrupts fixes this problem and the common AHCI driver works fine.

* ahci: extend data io wait to 10sMark Langsdorf2015-06-12-1/+1
| | | | | | | | | | | The AHCI driver currently waits 5s before timing out when sending a data command to a drive. Some drives take upwards of 8s to respond to the initial data command while they're spinning up. Increase the data io timeout to 10s so that those drives can be found on initial scsi scan.

* x86: ahci: Make sure interface is not busy after enabling the portBin Meng2015-01-23-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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).

* ahci: Fix data abort on multiple scsi resets.Roger Quadros2014-04-02-7/+16
| | | | | | | | | | | | | | | | | | | 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: Expand HDD Logical Block addressability up to 32 bitsWalter Murphy2012-11-02-4/+8
| | | | | | | | | | | | | | | | | | Currently, this driver uses a 28bit interface to AHCI, this limits the number of blocks addressable to 2^28, or the max disk size to 512(2^28) or about 137GB. This change allows supporting drives up to about 2TB. Testing this is a bit difficult. There is test code that can be inserted into U-Boot that will write test patterns into certain unused blocks. These patterns can be manually checked using 'dd' after boot. Another way is to confirm the original error that exposed this bug is fixed. IOW: see if AU (Auto Update) will now work on the drive.

| | | | | | | | | | | | | | | | | | | | | | | | | Update the assignment of various physical memory buffers used by the SATA controller to explicitly be denoted as physical addresses. The memory is identity-mapped, so these function calls are a nop, but they provide good semantic documentation for any maintainers. The return value of virt_to_phys() is 'unsigned long'. On machines where sizeof(unsigned long) != sizeof(pointer), a cast through (uintptr_t) is needed to appease the compiler due to the potential of losing the upper 32 bits of the address. In compilation this scenario, a physical address could be 64-bits, yet the C pointer environment only allows 32-bit addresses; the constraint is that pointers cannot address more than 4Gb of memory and if virt_to_phys() ever returns an out-of-range value for the physical address, there are issues with emmory mapping which must be solved. However, since the memory is identify mappeed, there is no problem introducing the cast: the original pointer will reside in 32-bits, so the physical address will also be within in 32-bits.

| | | | | | | | | | | | | | | | | | | | | | | In the structure returned by the ATA identify device command, there are two fields which describe the device capacity. One is a 32 bit data type which reports the number of sectors as a 28 bit LBA, and the other is a 64 bit data type which is for a 48 bit LBA. If the device doesn't support 48 bit LBAs, the small value is the only value with the correct size. If it supports more, if the number of sectors is small enough to fit into 28 bits, both fields reflect the correct value. If it's too large, the smaller field has 28 bits of 1s, 0xfffffff, and the other field has the correct value. The AHCI driver is implemented by attaching to the generic SCSI code and translating on the fly between SCSI binary data structures and AHCI data structures. It responds to requests to execute specific SCSI commands by executing the equivalent AHCI commands and then crafting a response which matches what a SCSI disk would send. The AHCI driver now considers both fields and chooses the correct one when implementing both the SCSI READ CAPACITY (10) and READ CAPACITY (16) commands.
