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
2009-06-08FS#10048 : enable MMU and data cache on Sansa AMS to give a major speed upRafaël Carré
- cache IRAM and DRAM - map IRAM just next to DRAM to remove the need for -mlong-calls and reduce binsize - tweak delays in Fuze button code - tweak delays in Clip button code (down button sometimes doesn't respond anyway : an alternate driver is being worked on) Before reporting any problem, please check your filesystem or format your player from the OF git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21228 a1c6a512-1295-4272-9138-f99709370657

2008-11-06AS3525: use kernel_init() in bootloaderRafaël Carré
This way creation of scrolling thread doesn't risk crashing the system git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19026 a1c6a512-1295-4272-9138-f99709370657
2008-11-01Apply FS#9500. This adds a storage_*() abstraction to replace ata_*(). To do ↵Frank Gevaerts
that, it also introduces sd_*, nand_*, and mmc_*. This should be a good first step to allow multi-driver targets, like the Elio (ATA/SD), or the D2 (NAND/SD). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18960 a1c6a512-1295-4272-9138-f99709370657
