[PATCH 0/5] ARM: dts: at91: Improve sam9x60-curiosity

Hello everyone,

currently I have the Microchip SAM9X60-Curiosity board on my desk and
for evaluation purposes I'm trying to get it booting from NAND flash
without SD card.  This series contains a collection of patches I made on
that journey.  It's probably not the last set of patches, but I send it
out now before my holidays so anyone who's interested has some time to
look into it before I return to my desk in roughly two weeks. ;-)

Note: while I could access the I²C EEPROM populated on that board with
Linux v6.4 through nvmem and the 100 bytes content seem valid including
a MAC address attributed to Microchip, I could not do so in U-Boot.
That also means out of the box access to Ethernet is currently broken
without valid MAC address.

Note: I prepared the patches at the office, but sending them from home
now.  This is why I use two different mail addresses.

Greets
Alex
