scsi: fix compiler warning with DEBUG and 48bit LBAs

2015-07-11T12:01:54+00:00

Commit 2b42c9317db ("ahci: support LBA48 data reads for 2+TB drives")
introduced conditional code which triggers a warning when compiled
with DEBUG enabled:

In file included from common/cmd_scsi.c:12:0:
common/cmd_scsi.c: In function 'scsi_read':
include/common.h:109:4: warning: 'smallblks' may be used uninitialized in this function [-Wmaybe-uninitialized]
...

Since this is for debug only, take the easy way and initialize the
variable explicitly on declaration to avoid the warning.
(Fix a nearby whitespace error on the way.)

ahci: support LBA48 data reads for 2+TB drives

2015-06-12T20:52:32+00:00

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.

cmd_scsi: Enable SoC AHCI device on platforms with PCI

2015-04-22T16:14:56+00:00

Current driver assumes the AHCI is connected to PCI, this is not
true on some SoCs, e.g. LS1021A, which has PCI but the AHCI is
in SoC. This patch will enable embedded AHCI devices on platforms
with PCI.
PCI AHCI devices still can be used by commenting CONFIG_SCSI_AHCI_PLAT
option in head file.

scsi: bootstage: Measure time taken to scan the bus

2015-02-06T19:07:38+00:00

On some hardware this time can be significant. Add bootstage support for
measuring this. The result can be obtained using 'bootstage report' or
passed on to the Linux via the device tree.

scsi: Correct types of scsi_read/write()

2013-07-15T21:06:09+00:00

The block device expects to see lbaint_t for the blknr parameter. Change
the SCSI read/write functions to suit.

This fixes the following build warnings for coreboot:

cmd_scsi.c: In function ‘scsi_scan’:
cmd_scsi.c:119:30: error: assignment from incompatible pointer type [-Werror]
cmd_scsi.c:120:32: error: assignment from incompatible pointer type [-Werror]

part/dev_desc: Add log2 of blocksize to block_dev_desc data struct

2013-05-01T20:24:02+00:00

log2 of the device block size serves as the shift value used to calculate
the block number to read in file systems when implementing avaiable block
sizes.
It is needed quite often in file systems thus it is pre-calculated and
stored in the block device descriptor.
