if you use only one CS no need to specified all
we need to add macro per SoC for the hw CS used as GPIO so it's more clear

yes as you dopy &pioD 13 0 everywhere instead of doing
#define SAMA5D3_SPI_CS0_GPIO &pioD 13 GPIO_ACTIVE_LOW

so put the kernel & dts on UBI to have wareleveling on it too
and then we do not need to knwown the kernel/rootfs/dtc partition size and

Nothing else is connected to PE9, so I do not describe anything else in
the DTS. No need for ifdefs or anything else.

I use this layout. Do not force me to use another one. I own this board,
do what you want on boards that you are responsible for and let me do
what I want on boards that I am responsible for.
If I want to switch to another layout, I will do at the proper date.
