Bug#928870: GRUB does not report all partitions

[Heinrich Schuchardt]

Package: grub-efi-arm64
Version: 2.02+dfsg1-18
Severity: normal

I use U-Boot v2018.07-rc1 on a MACCHIATObin.

The UEFI shell reports these block devices and partitions:

FS4: Alias(s):HD0b:;BLK7:
/VenHw(e61d73b9-..)/SD(1)/SD(2)/HD(1,MBR,0x477bc392,0x2000,0x200000)
FS5: Alias(s):HD0c:;BLK8:
/VenHw(e61d73b9-..)/SD(1)/SD(2)/HD(2,MBR,0x477bc392,0x202000,0x200000)
FS6: Alias(s):HD0d:;BLK9:
/VenHw(e61d73b9-..)/SD(1)/SD(2)/HD(3,MBR,0x477bc392,0x402000,0x379e000)
FS0: Alias(s):HD0b0b:;BLK2:
/VenHw(e61d73b9-..)/Scsi(1,0)/HD(1,MBR,0x378e54c5,0x8000,0x38000)
FS1: Alias(s):HD0b0c:;BLK3:
/VenHw(e61d73b9-..)/Scsi(1,0)/HD(2,MBR,0x378e54c5,0x40000,0xc0000)
FS2: Alias(s):HD0b0d:;BLK4:
/VenHw(e61d73b9-..)/Scsi(1,0)/HD(3,MBR,0x378e54c5,0x100000,0xed7c2b0)
FS3: Alias(s):HD0b0e:;BLK5:
/VenHw(e61d73b9-..)/Scsi(1,0)/HD(4,MBR,0x378e54c5,0x800,0x7800)
BLK0: Alias(s):
/VenHw(e61d73b9-..)/eMMC(0)/eMMC(1)
BLK6: Alias(s):
/VenHw(e61d73b9-..)/SD(1)/SD(2)
BLK1: Alias(s):
/VenHw(e61d73b9-..)/Scsi(1,0)

grubaa64.efi is located on Scsi(1,0)/HD(2,..).
GRUB modules are on Scsi(1,0)/HD(3,..).

Booting fails. The GRUB rescue console reports:

grub> ls
(proc) (hd0) (hd1) (hd1,msdos3) (hd1,msdos2) (hd1,msdos1) (hd2)

So booting fails GRUB because it does not see the partitions on my harddisk.

GRUB should report existing partitions on all devices, especially the
one it is loaded from.

Best regards
