Cannot boot on a H2+ OTT box

[Icenowy]

The current images of fel-mass-storage failed to boot on a H2+ OTT box (Sunvell R69)

It stucks after:

[sun8i_fixup]: From boot, get meminfo:
        Start:  0x40000000
        Size:   1024MB
ion_carveout reserve: 160m@0 256m@0 130m@1 200m@1
ion_reserve_select: ion chipid  [0x2004620!
ion_reserve_common: ion reserve: [0x50000000, 0x60000000]!

Looking at the u-boot config used I used pretty optimistic values:

CONFIG_DRAM_CLK=624
CONFIG_SYS_CLK_FREQ=1008000000

I would try to downclock both CPU and DRAM - AFAIK this box has no CPU voltage switching and I wouldn't trust in DRAM quality in cheap TV boxes 😄

For the reference Armbian u-boot config for this device has

CONFIG_DRAM_CLK=576
CONFIG_SYS_CLK_FREQ=480000000
