[U-Boot] [PATCH v5 00/26] spl: Lightweight UBI and UBI fastmap support

[Ladislav Michl]

Core of this patch serie is based on Thomas's patchset:
https://patchwork.ozlabs.org/patch/367305/
https://patchwork.ozlabs.org/patch/367306/

This serie contains also changes needed to let single binary running
on IGEPv2 board equipped either with NAND or OneNAND flash memory:
igep0020_nand_defconfig is dropped and igep0020_defconfig modified
to support both flash memories. As many flash manipulatioin routines
do not expect flash reading failure (as chip is not present), fix
them too.

Now, first four flash sectors contains SPL as this is what Boot ROM
code expects and loads. The rest of flash is UBI managed: U-Boot,
its environment, kernel and rootfs are stored in UBI volumes.
As enviroment is stored in UBI volume, we need to know how is flash
partitioned very early. Also various board modifications come with
different geometry flash memories. To let this work two changes are
introduced: mtdpart code uses default partitions unless it is
explicitely told to do otherwise and support for runtime generated
default partitions has been added.

Changes in v5:
- dual license GPL/BSD

Changes in v4:
- drop unused name field from ubispl_load structure
- ipl_load returns lenght read

Changes in v3:
- move vol_id check to ubi_scan_vid_hdr to verify it has meaningfull value
  before testing ubi->toload
- fixed checkpatch errors except those present also in linux code

Changes in v2:
- rename nand_spl_read_flash to nand_spl_read_block and optimize it.
- fixes ubi_calc_fm_size to include also sizeof(struct ubi_fm_sb)
- dropped private copy of ubi-media.h
- ubi-wrapper.h now contains only needed definitions from ubi.h
  and ubi-user.h
- used return values from errno.h
