'0 | ..' and '0 << ...' don't help readability over just value saying it
(same with shifting 0). Also, unless the manual these come from uses
decimal here, hex is preferred. Thanks!

'0 | ...'. I agree, I'll remove this.
'0 << ...'
Aaaahhh... Yes, that's pretty useless here, the WTR bits are reserved bits
:-/
Decimal values: I'd like to keep them. This is DDR timing, the numbers mean
number of clock cycles minus one. So actually (1 <<
DV_DDR_SDTMR1_RRD_SHIFT) means that trrd=13.3333... ns (two clock cycles)
at 150 MHz. So I must calculate with these numbers and this is why I prefer
decimal over hex. I am lazy ;-)

Uh, sorry, they are not reserved. But a zero value here means that we
have one clock cycle (because it's number of clock cycles minus one).
So I'd like to keep the line because it will help others to see that
WTR is set to one clock cycle.

I'd say it's not obvious that a value of zero means one clock cycle, so
drop the define and just comment what the full value contains.

Support for variable length images like AIS image was introduced
in commit f0662105b674a3874227316abf8536bebc9b5995. A parameter
"-s" was also introduced to prohibit copying of the image file
automatically in the main program. However, this parameter
was implemented incorrectly and the image file was copied
nevertheless.

I'll change that.
The chaos above contains three commands:
1) I run the SPL through mkimage to add an AIS header for booting from SPI.
Since an empty config file (-n) is sufficient here I use /dev/null here.
2) I pad the result $(obj)spl/u-boot-spl.ais to $CONFIG_SPL_MAX_SIZE with
$(OBJCOPY): The result is $(obj)spl/u-boot-spl-pad.ais
3) Then I add $(obj)u-boot.bin with cat, the result is $(obj)u-boot.ais

right; i was wondering if we could chain these somehow. but i guess going
through intermediate files allows for catching errors that would get missed in
a pipeline.
