The vexpress Kconfig setup tries to be clever^Whelpful and selects some errata workarounds for certain revisions of the Cortex-A9 and PL310, which may be required depending on the core tile. Since the mach-vexpress can support A5, A7 and A15 coretiles, let's make errata workaround selection optional.

New Versatile Express platforms require Flattened Device Tree to
|
|
be passed to the kernel.
|
|
|
|
This option enables support for systems using Cortex processor based
|
|
ARM core and logic (FPGA) tiles on the Versatile Express motherboard,
|
|
for example:
|
|
|
|
- CoreTile Express A5x2 (V2P-CA5s)
|
|
- CoreTile Express A9x4 (V2P-CA9)
|
|
- CoreTile Express A15x2 (V2P-CA15)
|
|
- LogicTile Express 13MG (V2F-2XV6) with A5, A7, A9 or A15 SMMs
|
|
(Soft Macrocell Models)
|
|
- Versatile Express RTSMs (Models)
|
|
|
|
You must boot using a Flattened Device Tree in order to use these
|
|
platforms. The traditional (ATAGs) boot method is not usable on
|
|
these boards with this option.
|
|
|
|
If your bootloader supports Flattened Device Tree based booting,
|
|
say Y here.
