This series adds support for the Utilite Mini Computer. Like several
other i.MX6 based boards this one also wants to setup the SDRAM from
code rather than from a DCD table. This has previously limited the
barebox image size to the internal SRAM size. This series overcomes
this limitation. We now create the i.MX image from the pblx image
instead of the complete image including payload. With this the ROM
code only loads the initial portion to SRAM and we can setup the
SDRAM there. Afterwards we have to load the remaining image ourselves,
but it turned out require only very little code to load an image
from the SPI NOR flash. This series implements this mechanism for
i.MX6 on SPI NOR flash only, support for other SoCs and other devices
needs to be added to get this working in other cases.
