This series adds NVM Express driver support to U-Boot.
This series is based on previous RFC v2 patchset [1][2] done by Zhikang Zhang and Wenbin Song, as well as Jon Nettleton's fixes [3] on top of the RFC v1.
The patches are organized in a way that meets the requirement of upstream. Jon's fixes were squashed/integrated with a proper order in this series.
The original RFC driver was cleaned up a lot, to remove the compilation limitation on non-ARMv8 architecture (including a header file from armv8), drop the board_r.c modification, drop unnecessary PCI configuration space initialization, add 32-bit architecture support of readq/writeq operations, eliminate compiler warnings, as well as coding convention clean up, plus a fix to a bug that is exposed by QEMU platform.
Tested with an Intel SSD 750 series NVMe 400GB card, a Plextor NVMe SSD M8Pe Series 256GB card, on Intel Crown Bay board, as well as QEMU x86 emulation platform.
This series is available at u-boot-x86/nvme-working for testing.
