Currently the bmode "usb" uses BOOT_CFG1 to 0x01, -which means
BOOT_CFG1[7:4] is set to b0000. According to Table 8-7 Boot
Device Selection this is NOR/OneNAND and not Reserved.
Use 0x10 which leads to b0001, which is a Reserved boot device.
With that the SoC reliably falls back to the serial loader.

i.MX6ULL has two 128 bits fuse banks, bank 7 and bank 8,
while other banks use 256 bits. So we have to adjust the
word and bank index when accessing the bank 8.
When in command line `fuse read 8 0 1`, you can image
`fuse read 7 4 1` in the ocotp driver implementation for 6ULL.
When programming, we use word index, so need to fix bank7/8 programming
for i.mx6ull.
For example: fuse prog 8 3 1; The word index is (8 << 3 | 3) --> 67.
But actully it should be (7 << 3 | 7) ---> 63.

When using SPL on i.mx6 we frequently notice some DDR initialization
mismatches between the SPL code and the non-SPL code.
This causes stability issues like the ones reported at 7dbda25ecd
("mx6ul_14x14_evk: Pass refsel and refr fields to avoid hang") and also:
http://lists.denx.de/pipermail/u-boot/2016-September/266355.html .
As the non-SPL code have been tested for long time and proves to be reliable,
let's configure the DDR in the exact same way as the non-SPL case.
The idea is simple: just use the DCD table and write directly to the DDR
registers.
Retrieved the DCD tables from:
board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg
and
board/freescale/mx6sabresd/mx6qp.cfg
(NXP U-Boot branch imx_v2015.04_4.1.15_1.0.0_ga)
This method makes it easier for people converting from non-SPL to SPL code.
Other benefit is that the SPL binary size is reduced from 44 kB to 39.9 kB.
