initial builds of OSK5912 boards need srst_pulls_trst
This is clearly noted in the hardware spec (section 5.2.3); it works around a chip erratum: "If the MPU_RESET signal is used, it may cause the EMIFS bus to lock." I seem to have a board with such an initial build. The chip is labeled XOMAP. Presumably, parts without that "X" prefix (eXperimental) resolve this.

# The TI-14 pin needs "trst_only", and J1 connecting 2 & 3.

reset_config trst_and_srst separate

# NOTE: boards with XOMAP parts wire nSRST to nPWRON_RESET.
|
||||
# That resets everything -- including JTAG and EmbeddedICE.
|

# So they must use "reset_config srst_pulls_trst".
|

# NOTE: an expansion board could add a trace connector ... if
|

# it does, change this appropriately. And reset_config too,
|
||||
# assuming JTAG_DIS reroutes JTAG to that connector.
