imx-mkimage: remove our .bb file and add a .bbappend
Every task in this recipe is already supported in the same way in the meta-freescale layer, so just keep the .bbappend file to select SRCBRANCH and SRCREV. The DDR patch can be removed since that source code is now included into the SCFW project. https://jira.digi.com/browse/DUB-881 Signed-off-by: Gonzalo Ruiz <Gonzalo.Ruiz@digi.com>

Subject: [PATCH] cc8x: configure DDRC for Micron MT53B256M32D1
|
|
||||||
|
|
||||||
The main differences to NXP part are:
|
|
||||||
- 1 rank, instead of 2.
|
|
||||||
- 4Gb density per channel, instead of 12.
|
|
||||||
- tRFC = 180 ns, instead of 280 ns. This also affects tXSR, tXS
|
|
||||||
- Reordering of the data bus lines.
|
|
||||||
|
|
||||||
These were calculated using Excel aid sheet:
|
|
||||||
