 We found that some serial console may pull TX line to GROUND during board
 boot time. Airoha uses TX line as one of it's BOOT pins. This will lead

-Subject: [PATCH 1/2] spi: airoha-snfi: make compatible with EN7523 SoC
-
-The driver is fully compatible with EN7523 based SoCs, so add
-corresponding compatible string.
-
-This driver is better than en7523-spi because it supports DMA.
-Measurements shows that DMA based flash reading is 4 times faster
-than non-dma one.
