2010-06-11FS#11335 by me: make ARM assembly functions thumb-friendlyRafaël Carré
We can't pop into pc on ARMv4t when using thumb: the T bit won't be modified if we are returning to a thumb function Code running on ARMv4t should use the new ldrpc / ldmpc macros instead of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc} No modification on pure ARM builds and ARMv5+ Note: USE_THUMB is currently never defined, no targets can currently be built with -mthumb, see FS#6734 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26756 a1c6a512-1295-4272-9138-f99709370657

2010-05-06Move c/h files implementing/defining standard library stuff into a new libc ↵Thomas Martitz
directory, also standard'ify some parts of the code base (almost entirely #include fixes). This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25850 a1c6a512-1295-4272-9138-f99709370657
2010-03-08Fix a bunch of boot.lds files so that they build with newer ld. The ↵Thomas Martitz
stack/bss sections need NOLOAD. otherwise the linker would try to include those into the binary. I don't know why this ever worked with our current ld version. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25078 a1c6a512-1295-4272-9138-f99709370657
2010-03-03FS#10756 - Free unused init codeThomas Martitz
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
2009-10-20Convert lcd_activation callbacks to use the event system to allow for ↵Thomas Martitz

Removed corresponding functions from the core and plugin api. Bump min version and sort. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23302 a1c6a512-1295-4272-9138-f99709370657

2009-06-17Sansa c200v2 : lcd & backlight support, using the c200v1 lcd driverRafaël Carré
The LCD driver is unified and lcd_send_command now takes 2 arguments : the command and its argument. If there is no argument, it's set to 0 and a NOP command is issued If there is more than one argument (set X/Y address), the 2nd argument is sent as a 2nd command, and a NOP command is issued after it. Benefit : c200v2 transfers the command and the argument in one 16 bits transfer Performance should not be affected since commands without argument are only used in lcd_init() and lcd_enable() lcd_send_data() now transfers whole lines (or columns) instead of single pixels yuv is disabled for c200v2 for now Some buttons can be read, including left button (bit 6 of DBOP_DIN), but for some reason they have no effect in rockbox: to be investigated git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21321 a1c6a512-1295-4272-9138-f99709370657

a) lcd_enabled() is now lcd_active(), and is available for HAVE_LCD_SLEEP only targets (e.g. ipod video) too. It was depandent on HAVE_LCD_ENALE only before b) rename the hook accordingly, and implement the hook for other other targets too (e.g. the clip [the only mono target with lcd_enable/lcd_sleep yet, so the code is still in the lcd driver], ipod, fuze, c200) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20331 a1c6a512-1295-4272-9138-f99709370657

how power inputs are sensed. Clean SIMULATOR stuff out of target files. Get rid of USB charging option on targets that don't support it or don't implement it yet. Menu string remains to avoid language incompatibility but should be removed on next cleanup for targets not using it (notice in english.lang). global_settings becomes incompatible for some builds and so plugin API version is incremented. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19315 a1c6a512-1295-4272-9138-f99709370657
