[Mitsyanko Igor]

Changelog
v3->v4
 - PATCH 1/3 rebased to current master;
 - Fixed .start field use during vmstate save/load;
 - added get_bufsize() NULL pointer check;
 - patches 2-4 merged into patches 2-3 

v2->v3:
 - PATCH 2/3 splitted into smaller patches 2-4/5.
 - SDState structure rearrengment dropped.

v1->v2:
 PATCH 1/3: 
 - .calc_size field replaced with .get_bufsize field in VMStateField;
 - .size_offset removed completely, macros based on it rewritten to use
 new .get_bufsize field.
 PATCH 2/3:
 - all binary variables in SDState now have bool type;
 - SDState structure rearranged to ensure alignement;
 - sd_init(), sd_enable() now receive bool;
 - new version of PATCH 1/3 now used to save wp_groups array;
 PATCH 3/3:
 - DMA transfers modified and now operate with data blocks of
 BLKSIZE only, like real hardware does;
 - reset procedure optimized;
 - new version of PATCH 1/3 now used to save fifo_buffer.

First patch of this patch set modifies existing VMStateField interface
to ease save/restore functionality implementation for device's dynamically
allocated buffers. This modification is used later in second patch to
implement SD card's VMStateDescription structure.
Fourth patch adds imlementation of new device: SD host controller fully
compliant with "SD host controller specification version 2.00". It also
uses vmstate field modification introduced in first patch.

Mitsyanko Igor (4):
  vmstate: introduce get_bufsize entry in VMStateField
  hw/sd.c: add SD card save/load support
  hw/sd.c: convert SD state binary variables to bool
  hw: Introduce spec. ver. 2.00 compliant       SD host controller
