Hello Simon,
U-Boot HEAD qemu-86_defconfig cannot discover an IDE disk with one FAT
partition in qemu-system-x86_64.
By bisection I found this patch.
b7c6baef2891ce8978cbfddb66e944943473ac21
x86: Convert MMC to driver model
With this patch I get
IDE: Bus 0: OK Bus 1: OK
Device 0: Model: QEMU HARDDISK Firm: 2.5+ Ser#: QM00001
Type: Hard Disk
Supports 48-bit addressing
Capacity: 128.0 MB = 0.1 GB (262144 x 512)
** Can't read Driver Desriptor Block **
Device 1: not available
Device 2: Model: QEMU Firm: 2.5+ Ser#: QEMU DVD-ROM
Type: Removable CD ROM
Capacity: not available
Device 3: not available
=> ide info

Without the patch I get=> ide info
Device 0: Model: QEMU HARDDISK Firm: 2.5+ Ser#: QM00001
Type: Hard Disk
Supports 48-bit addressing
Capacity: 128.0 MB = 0.1 GB (262144 x 512)
Device 2: Model: QEMU Firm: 2.5+ Ser#: QEMU DVD-ROM
Type: Removable CD ROM
Capacity: not available
I think we observe two independent errors here:
- The hard disk Device 0 is not read.
- The ide command stops at the first device that is not available.
I guess only the first is caused by your patch.
Best regards
Heinrich
