spl: nand: sunxi: use PIO instead of DMA

SPL support was first written to support only the earlier generations of
Allwinner SoCs, and was only really enabled on the A13 / GR8. However,
those old SoCs had a DMA engine that has been replaced since the A31 by
another DMA controller that is no longer compatible.

Since the code directly uses that DMA controller, it cannot operate
properly on the later SoCs, while the NAND controller has not changed.

There's two paths forward, the first one would have been to add support
for that DMA controller too, the second to just remove the DMA usage
entirely and rely on PIO.

The later has been chosen because CPU overload at this stage is not an
issue and it makes the driver more generic, and easier to understand.

Miquel Raynal [Wed, 28 Feb 2018 19:51:43 +0000 (20:51 +0100)]
spl: fix binman_sym output check

A previous commit introduced the use of binman in the SPL.

After the binman_sym call over the 'pos' symbol, the output value is
checked against BINMAN_SYM_MISSING (-1UL). According to the
documentation (tools/binman/README), when it comes to the 'pos'
attribute:

pos:
This sets the position of an entry within the image. The first
byte of the image is normally at position 0. If 'pos' is not
provided, binman sets it to the end of the previous region, or
the start of the image's entry area (normally 0) if there is no
previous region.

So instead of checking if the return value is BINMAN_SYM_MISSING, we
should also check if the value is not null.

The failure happens when using both the SPL file and the U-Boot file
independently instead of the concatenated file (SPL + padding + U-Boot).
This is because the U-Boot binary file alone does not have the U-Boot
header while it is present in the concatenation file. Not having the
header forces the SPL to discover where it should load U-Boot. The
binman_sym call is supposed to do that but fails. Because of the wrong
check, the destination address was set to 0 while it should have been
somewhere in RAM. This, obviously, stalls the board.

cmd: part: Allow passing partition name to start and size

Allow passing the partition name to "part start" and "part size"
commands, so we can avoid magic numbers in the environment.

Consider one real use-case: in include/environment/ti/boot.h we have
commands like these:

    setenv boot_part 9
    part start mmc ${mmcdev} ${boot_part} boot_start
    part size mmc ${mmcdev} ${boot_part} boot_size
    mmc read ${loadaddr} ${boot_start} ${boot_size}

is 10. We will need to fix commands above. And anyone who relies on
these boot commands, will need to change them accordingly, too (this was
an actual case in our lab while testing Linux boot on Android
