Michael Sevakis 830531b7d4 i.MX31: Simplify nested interrupt handling. Give SVC mode its own stack by grabbing the FIQ stack that's just been taking up space. Just get rid of all FIQ setup since it isn't used anyway.

gigabeat-s Shuffle some functions around so that interfacing with playback.c in particular isn't required. Though playback does finish the audio init, pcm doesn't care who does it. 2011-09-01 12:15:43 +00:00
app.lds Some static data is only used by .init functions. Add .initdata to declare such data (otherwise section conflicts arise). For i.MX31, use INITDATA_ATTR in the appropriate places. 2011-01-08 20:42:51 +00:00
ata-imx31.c Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. 2011-03-02 08:49:38 +00:00
ata-target.h i.MX31: Busy wait for a couple microseconds at most then sleep until next tick when polling drive status. This prevents pointless jumps to overdrive speed from perceived high load when waiting for lengthy ops to complete such as spinup and sleep. 2011-01-22 09:23:31 +00:00
avic-imx31.c i.MX31: Simplify nested interrupt handling. Give SVC mode its own stack by grabbing the FIQ stack that's just been taking up space. Just get rid of all FIQ setup since it isn't used anyway. 2011-10-14 00:01:41 +00:00
avic-imx31.h i.MX31: Simplify nested interrupt handling. Give SVC mode its own stack by grabbing the FIQ stack that's just been taking up space. Just get rid of all FIQ setup since it isn't used anyway. 2011-10-14 00:01:41 +00:00
boot.lds Some static data is only used by .init functions. Add .initdata to declare such data (otherwise section conflicts arise). For i.MX31, use INITDATA_ATTR in the appropriate places. 2011-01-08 20:42:51 +00:00
ccm-imx31.c Remove atomic register bit manipulation functions from i.MX and s3c target code and introduce generic functions for ARM (bitmod32, bitset32, and bitclr32). Multiprocessor support is possible but just not implemented at the moment, only interrupt lockout. 2010-06-30 02:02:46 +00:00
ccm-imx31.h i.MX31/Gigabeat S: Implement frequency and voltage scaling-- 1.6V for 528MHz, and 1.35V for 264MHz and 132MHz. Keep DPTC overdrive ( > 400MHz) voltage scaling off for now because of uncertainties. Simplify the (working) mess later. 2010-04-23 15:32:50 +00:00
crt0.S i.MX31: Simplify nested interrupt handling. Give SVC mode its own stack by grabbing the FIQ stack that's just been taking up space. Just get rid of all FIQ setup since it isn't used anyway. 2011-10-14 00:01:41 +00:00
debug-imx31.c Move dbg_hw_info() into target tree. FS#11735 by me 2011-06-05 10:26:06 +00:00
debug-target.h Move dbg_hw_info() into target tree. FS#11735 by me 2011-06-05 10:26:06 +00:00
dvfs_dptc-imx31.c i.MX31: Simplify nested interrupt handling. Give SVC mode its own stack by grabbing the FIQ stack that's just been taking up space. Just get rid of all FIQ setup since it isn't used anyway. 2011-10-14 00:01:41 +00:00
dvfs_dptc-imx31.h i.MX31: Now that it matters because there's a debug screeen that allows changing things while running, some DVFS/DPTC stuff has to be done more carefully. Trim out some stuff and group functions better as well. 2011-01-23 20:21:35 +00:00
gpio-imx31.c Configure Gigabeat S with EABI compiler by default. Implement the INIT section that this enables (due to selective need for long calls). Remove pcm_postinit from INIT section since it's asynchronous. Disable strict aliasing on SPC codec for now just to shut it up. 2010-06-11 14:39:35 +00:00
gpio-imx31.h i.MX31/Gigabeat S minor cleaning: Make HW access more obvious in places I forgot to do earlier. Reduce the number of structs that need to be filled-out for some drivers just to simplify a little. Change some types. 2010-05-07 10:53:19 +00:00
i2c-imx31.c Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. 2011-03-02 08:49:38 +00:00
i2c-imx31.h i.MX31: Make some style changes to some driver code so that hardware vs. variable access is more obvious to the eye. Change a few data types and qualifiers. No functional differences. 2010-05-07 02:29:18 +00:00
iomuxc-imx31.c Remove atomic register bit manipulation functions from i.MX and s3c target code and introduce generic functions for ARM (bitmod32, bitset32, and bitclr32). Multiprocessor support is possible but just not implemented at the moment, only interrupt lockout. 2010-06-30 02:02:46 +00:00
iomuxc-imx31.h i.MX31: Add some enums and a couple helper functions to make dealing with pin muxing and pad configuration a bit more sane. Convert any existing code which changes mux/pad settings to use helpers. 2010-04-23 13:46:04 +00:00
mc13783-imx31.c Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. 2011-03-02 08:49:38 +00:00
mmu-imx31.c Gigabeat S/i.MX31: Sort files in the /target tree into things that are SoC-generic (into /imx31) and player-specific (into /gigabeat-s, based upon current appearances). Move i2s clock init into the appropriate file. Housekeeping only-- no functional changes. 2010-04-09 01:21:53 +00:00
mmu-imx31.h Gigabeat S/i.MX31: Sort files in the /target tree into things that are SoC-generic (into /imx31) and player-specific (into /gigabeat-s, based upon current appearances). Move i2s clock init into the appropriate file. Housekeeping only-- no functional changes. 2010-04-09 01:21:53 +00:00
rolo_restart_firmware.S Introduce NORETURN_ATTR wrapper for __attribute__((noreturn)), using this and a bit further cleanup in main gets rid of a warning when compiling for android. 2010-08-12 13:38:25 +00:00
sdma-imx31.c i.MX31: Make DMA ISR call loop a bit more efficient. 2010-06-30 07:08:10 +00:00
sdma-imx31.h Gigabeat S: Implement MDMA and UDMA disk access for bootloader and main binary. Add a needed SDMA API to check channel errors. Increase audio DMA channels' priority as required. Reads and writes measure faster accross all test_disk tests and especially at 4KB and 1MB. 2009-03-12 06:31:40 +00:00
sdma_script_code.h Some static data is only used by .init functions. Add .initdata to declare such data (otherwise section conflicts arise). For i.MX31, use INITDATA_ATTR in the appropriate places. 2011-01-08 20:42:51 +00:00
sdma_struct.h Fix tabs 2010-01-03 10:19:43 +00:00
serial-imx31.h Gigabeat S/i.MX31: Sort files in the /target tree into things that are SoC-generic (into /imx31) and player-specific (into /gigabeat-s, based upon current appearances). Move i2s clock init into the appropriate file. Housekeeping only-- no functional changes. 2010-04-09 01:21:53 +00:00
spi-imx31.c Configure Gigabeat S with EABI compiler by default. Implement the INIT section that this enables (due to selective need for long calls). Remove pcm_postinit from INIT section since it's asynchronous. Disable strict aliasing on SPC codec for now just to shut it up. 2010-06-11 14:39:35 +00:00
spi-imx31.h Gigabeat S: Implement LCD contrast, invert and flip modes. Enhance LCD power management. Include init data but it's not needed yet (identical to Gigabeat F). 2010-05-18 23:50:00 +00:00
uart-imx31.c Split off target-specific parts from firmware/drivers/serial.c 2011-04-23 08:23:07 +00:00
