. add fatfs umon cli to it. unmodified from the umon 1.19
distribution, apache-licensed.
. also add dosfs from the umon 1.19 distribution, which is
similarly liberally licensed.
. increase available 'ROM' size to 128kB minus
1kB secure + 18kB reserved (numbers from uboot wiki).
. no unaligned access - needed to access fields in
on-disk structs without gcc generating unaligned
access instructions (causes data abort exceptions)
. turn on shellvars for BBB as they are needed to
connect FATFS to the SD i/o functions

An MLO file will be created from the concatenation of a corresponding GP header
and the uMon image. A GP header must be prepended to the uMon image when
booting from non-XIP devices. Refer to the AM335x TRM, Section 26.1.9 for more
information.
These type of images have been tested when booting the MLO file from an SD card
with a FAT32 primary partition marked as Active.

The internal SRAM of the AM335x/BBB is 109KB. First half is allocated to Umon code and
nonvolatile data while the second half is allocated to volatile data.

nand740.c is for the NAND device found on the CSB740. Hence, the file is not
relevant to the BBB. The file has also been removed from the compilation
process in Makefile.

The AD7843 Interface routines are not relevant to the BBB, therefore it is removed.
ad7843.c has been removed from the compilation process in Makefile.
|
|
|
|
| |
Additionally, the compilation of these files were excluded in the Makefile

'boot' and 'ramtst' targets in Makefile need to have prerequisite makefile
as "Makefile" instead of "makefile".

* Changed PLATFORM and TGTDIR to match BBB target
* Fixed inclusion of .make files
