If U-Boot is loaded and started from TF-A (you need to change SYS_TEXT_BASE to 0x60000000), it will hang up at flash initialization.
If secure mode is off (default, or -machine virt,secure=off) at qemu, it will provide dtb with two flash memory banks: flash@0 { bank-width = <0x4>; reg = <0x0 0x0 0x0 0x4000000 0x0 0x4000000 0x0 0x4000000>; compatible = "cfi-flash"; }; If secure mode is on, on the other hand, qemu provides dtb with 1 bank: flash@0 { bank-width = <0x4>; reg = <0x0 0x4000000 0x0 0x4000000>; compatible = "cfi-flash"; };
As a result, flash_init()/flash_get_size() will eventually fail. With this patch applied, relevant CONFIG values are modified.
