Subject: scsi: Add ata_swap_buf_le16() to support big-endian platforms
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9201200c6fefd319428c90a831790858a7d292f7;p=u-boot.git

scsi: Add ata_swap_buf_le16() to support big-endian platforms

Otherwise the output will look like this on MIPS Octeon NIC23:

  Device 0: (0:0) Vendor: ATA Prod.: aSDnsi klUrt aII Rev: 4X11
            Type: Hard Disk
            Capacity: 457862.8 MB = 447.1 GB (937703088 x 512)

instead of this version:

  Device 0: (0:0) Vendor: TA Prod.: SanDisk Ultra II Rev: X411
            Type: Hard Disk
            Capacity: 457862.8 MB = 447.1 GB (937703088 x 512)
