Actually, I guess booting directly from ROM using 0xffff is easier for
testing for now.
Speaking of testing:
I'm not sure what is omap_l3_smx neccessary for, but it does not work.
[ 0.223297] omap_l3_smx omap_l3_smx.0: couldn't request debug irq
[ 0.223419] omap_l3_smx: probe of omap_l3_smx.0 failed with error
-22
There is some fun in pinmuxing:
[ 0.247131] irq: no irq domain found for /ocp/pinmux@48002030 !
[ 0.248291] irq: no irq domain found for /ocp/pinmux@48002030 !
...
[ 0.384826] omap_i2c 48070000.i2c: could not find pctldev for node
/ocp/pinmux@48002030/pinmux_i\
2c1_pins, deferring probe

2c3_pins, deferring probe
[ 0.385375] platform 48060000.i2c: Driver omap_i2c requests probe

And serial has some problems:
[ 0.482208] of_get_named_gpiod_flags: can't parse 'rts-gpio'
property of node '/ocp/serial@4806c\
000[0]'
[ 0.482513] omap_uart 4806c000.serial: ttyO1 at MMIO 0x4806c000

is a OMAP UART1
[ 0.484588] of_get_named_gpiod_flags: can't parse 'rts-gpio'
property of node '/ocp/serial@49020\
000[0]'
[ 0.484771] omap_uart 49020000.serial: ttyO2 at MMIO 0x49020000
(irq = 224, base_baud = 3000000)\
is a OMAP UART2
There's a lot of noise from probe defferal :-(. And it looks like mmc
properties have some problems:
[ 0.739349] of_get_named_gpiod_flags: can't parse 'wp-gpios'
property of node '/ocp/mmc@4809c000\
[0]'
[ 0.740142] omap_hsmmc 4809c000.mmc: unable to get vmmc regulator

[ 0.740692] of_get_named_gpiod_flags: can't parse 'wp-gpios'
property of node '/ocp/mmc@480b4000\

omapfb reports problems, but seems to work ok:
[ 0.990386] omapfb omapfb: cannot parse default modes
[ 1.004791] Console: switching to colour frame buffer device 100x30
[ 1.073150] omapfb omapfb: using display 'lcd' mode 800x480
Best regards,
