gigabeat-s 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
app.lds Gigabeat S: INIT section wasn't properly overlapping the uninitialized areas thus wasn't being reclaimed. 2010-06-30 05:49:56 +00:00
ata-imx31.c Gigabeat S: Use statically initialized channel descriptors. Also, there's no need for them to be in non-cached memory since they're only used on the AP side. 2010-06-24 08:40:05 +00:00
ata-target.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
avic-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
avic-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
boot.lds Gigabeat S: Reclaim about 800K of memory that was laying unused. Get rid of DEVBSS_ATTR for this target and implement as NOCACHEBSS_ATTR. Plugin and codec buffers move so all that is now incompatible (do full update). No version increase for plugins/codecs because the loader will reject them. 2010-05-08 07:45:34 +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 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
debug-imx31.c Move c/h files implementing/defining standard library stuff into a new libc directory, also standard'ify some parts of the code base (almost entirely #include fixes). 2010-05-06 21:04:40 +00:00
debug-target.h Updated our source code header to explicitly mention that we are GPL v2 or 2008-06-28 18:10:04 +00:00
dvfs_dptc-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
dvfs_dptc-imx31.h i.MX31/Gigabeat S: This should fix stability problems. One problem was to start using the DVFS controller properly so that interrupts will be masked at the lowest and highest frequency indexes. Millions of useless interrupts were occurring at 132MHz because its index was 2, not 3, which masks it automatically when it can't go slower. Stopping the flood was enough to actually see the difference in general. IRQ must be disabled when fiddling with the CCM registers and only enabled when waiting for voltage ramp as having them enables also causes spurious DVFS ints. Implement interruptible ISR pro/epilogue more safely (always using IRQ stack even in SVC mode handling). Fix an improper inequality in DVFS code (which set regs for down when going up and v.v.). Misc. support changes. Have internal tables take less RAM. 2010-05-06 03:23:51 +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).

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 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.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

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.
