- 512 MiB SDRAM
- 4 GiB MLC NAND (Micron MT29F32G08CBACAWP or Hynix H27UBG8T2BTR)
- USB host
- LCD 800x480
- HDMI
- CAN
Note that the NAND support is still missing. As its currently not
supported in mainline for sunxi and especially for these MLC
devices.
The original plan was to also provide a dtsi for the ICnova SoM,
to put all the SoM internal nodes / properties there. But as I
don't have a clear overview of the SoM specific and baseboard
specific differences, I'm putting all in one dts for now. Once
somebody pushed support for some other baseboard using the
A20 SoM from Incircuit (e.g. the ADB4006 reference design), this

cpu_relax() on ARC has been barrier only for SMP (and no-op for UP). Per
recent discussions, it is safer to make it a compiler barrier
unconditionally.

ARCompact and ARCv2 only have ASL, while binutils used to support LSL as

Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)
- So move mem_service exception handler from common code into ARCv2 code.
- In ARCompact code, define mem_service as L2 interrupt handler which
just drops down to pure kernel mode and goes of to enqueue SIGBUS
