Thomas Martitz	f8edc32589	FS#10756 - Free unused init code ... Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back. Only implemented for PP and as3525 so far. More targets could be added, as well as more functions. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25013 a1c6a512-1295-4272-9138-f99709370657	2010-03-03 23:20:32 +00:00
Michael Sevakis	ec67912b63	Reclaim .iram areas in DRAM by overlapping their load addresses with the uninitialized data sections. I did what I could test out-- not any flash image linker scripts or other target processors. Move any .iram copies in crt0.S's to be the first operation even if not _strictly_ necessary to be emphatic (aka. 'beware'). ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20061 a1c6a512-1295-4272-9138-f99709370657	2009-02-20 02:33:40 +00:00
Jens Arnold	2bbacf89fe	Make sure the linker considers crt0*.o before all files specified on the command line by using STARTUP() instead of INPUT() in the .lds. Using INPUT() makes the linker process crt0*.o after all files specified on the command line, making linking fail if there are librockbox.a members which are only referenced by crt0*.o. Remove the hackaround that was needed for building the gigabeat S bootloader before (aka UIE() problem). ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17289 a1c6a512-1295-4272-9138-f99709370657	2008-04-29 06:19:32 +00:00
Frank Gevaerts	7a2d9ddb08	move some data around to place qh_array at the start of iram. This saves up to about 2k iram on PP ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17194 a1c6a512-1295-4272-9138-f99709370657	2008-04-20 18:43:47 +00:00
Robert Kukla	feb3b588e3	explicitly align the ibss section by adjusting _iramend - fixes hang on m:robe (and potential problem on other arm targets) ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17024 a1c6a512-1295-4272-9138-f99709370657	2008-04-07 18:24:23 +00:00
Michael Sevakis	05099149f1	Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit). ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16981 a1c6a512-1295-4272-9138-f99709370657	2008-04-06 04:34:57 +00:00
Karl Kurbjun	ef62d6891a	Split up app.lds to the respective target directories. The portalplayer devices replicate app.lds since their target tree doesn't follow a syntax typical to the newer arm targets - the portalplayers could be cleaned up further. boot.lds and plugin.lds still need to be cleaned up. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16651 a1c6a512-1295-4272-9138-f99709370657	2008-03-13 03:48:23 +00:00
