[En-Nut-Discussion] OPTIONs for ROM/HEX/BIN Generation

[Uwe Bonnes]

Hello,

Thu, 19 Feb 2009 with the subject:  Proposed addition to app/Makerules

I tried to discuss the addition of BINFLAGS option to have influence on the
ROM/HEX/BIN generation.  No feedback, proposed patch also not applied. 

Was something wrong with the proposal?

Bye

b.t.w: find the old mail appended.

appended patch
- Adds "-R .eeprom" to the rom and bin target
- Adds a BINFLAGS variable  to the hex/rom/bin target

The BINFLAG comes handy if the local Makefile defines additional sections
like:

LDFLAGS += -Wl,--section-start=.aram=0x801100 
LDFLAGS += -Wl,--section-start=.fpga=0x80e000

and these sections should be exclude from the targets too, like

BINFLAGS += -R .aram -R .fpga

Fore me, .aram is additional RAM memory and memory mapped FPGA registers,
that are only detected in main().

Any comments?

Thanks
