SubjectRe: [PATCH] ARM: dts: nuvoton: Fix flash layout
Hi, Tom.

Yes, I'm using it for testing on real hardware.

BTW. Recent u-boot doesn't work with SD cards. The card doesn't
detect. The last working version was this one:

https://github.com/Nuvoton-Israel/nuvoton-info/tree/master/npcm7xx-poleg/evaluation-board/sw_deliverables/npcm7xx_v2.3

However, u-boot from igps repo:

https://github.com/Nuvoton-Israel/igps/tree/master/ImageGeneration/versions

Has issues too. It doesn't allow me to read more than 4k bytes once at
a time. Thus, to flash the stuff I have manually read chunks from the
SD-card: fat load doesn't work at all and I write that data in raw
partition.
