[Qemu-devel] [PATCH 00/12] bugfix and qdevify NAND and ONENAND devices

[Peter Maydell <peter.maydell@linaro.org>]

This patchseries is more goodies from the Meego tree. Specifically, various
bug fixes to hw/nand and hw/onenand, plus conversion of both to sysbus.

[An advance note on the next thing due to come out of the pipe: qdeving
nand and onenand allows us to move to qdevification of omap_gpmc, which
takes both of those (and other things) as 'downstream' devices. That
change will make it accept arbitrary SysBus devices as its 'downstream'
devices rather than the current setup of taking an opaque pointer and a
pair of resize/unmap function pointers. (There are also patches which add
NAND support so you can tell omap_gpmc "this is a NAND device" and it then
uses the nand_setpins/nand_getpins/nand_setio interface.) The rationale for
using SysBus there rather than defining some new kind of bus is that you
want to be able to plug any random thing into it; for instance the Overo
board has a lan9118 ethernet controller hanging off the GPMC. ]

A note on dependencies:
 * This patch depends on the omap gpio patchset (although more textually
   than seriously semantically)
 * the six nand patches and the six onenand patches are broadly independent
   of each other

Juha Riihimäki (9):
  hw/nand: Support large NAND devices
  hw/nand: Support devices wider than 8 bits
  hw/nand: Support multiple reads following READ STATUS
  hw/nand: qdevify
  onenand: Handle various ID fields separately
  onenand: Ignore zero writes to boot command space
  hw/onenand: program actions can only clear bits
  hw/sysbus: Add sysbus_mmio_unmap() for unmapping a region
  hw/onenand: qdevify

Peter Maydell (3):
  hw/nand: Pass block device state to init function
  hw/nand: Writing to NAND can only clear bits
  onenand: Pass BlockDriverState to init function
