Subject: arm64: dts: rockchip: add product-data eeproms to QNAP TS433
X-Git-Url: http://git.dujemihanovic.xyz/posts?a=commitdiff_plain;h=373a336e2f177c9ecb2e92e4f114031d7adeedf4;p=u-boot.git

arm64: dts: rockchip: add product-data eeproms to QNAP TS433

The device contains two i2c-connected eeproms holding some product-
specific values. One sitting on the mainboard and one on the statically
connected backplane.

While the eeprom chips themself have a size of 512 byte, the eeprom data
only uses 256 byte each, probably to stay compatible with other models.
