From a420561bf8315f60c290ea41aaa7e80f410c592d Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Sat, 8 May 2010 07:45:34 +0000 Subject: 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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25895 a1c6a512-1295-4272-9138-f99709370657 --- firmware/export/imx31l.h | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) (limited to 'firmware/export/imx31l.h') diff --git a/firmware/export/imx31l.h b/firmware/export/imx31l.h index 66ae0acc4d..ea92d059cc 100644 --- a/firmware/export/imx31l.h +++ b/firmware/export/imx31l.h @@ -35,14 +35,18 @@ #define FRAME_SIZE (240*320*2) /* Rockbox framebuffer address, not retail OS */ #define FRAME_PHYS_ADDR (TTB_BASE_ADDR - FRAME_SIZE) -#define FRAME ((void *)(FRAME_PHYS_ADDR-CSD0_BASE_ADDR)) +#define FRAME ((void *)(FRAME_PHYS_ADDR+0x100000-CSD0_BASE_ADDR)) + +#define CACHEALIGN_SIZE 32 +#define NOCACHE_BASE CSD0_BASE_ADDR -#define DEVBSS_ATTR __attribute__((section(".devbss"),nocommon)) /* USBOTG */ #define USB_QHARRAY_ATTR __attribute__((section(".qharray"),nocommon,aligned(2048))) #define USB_NUM_ENDPOINTS 8 -#define USB_DEVBSS_ATTR DEVBSS_ATTR +#define USB_DEVBSS_ATTR NOCACHEBSS_ATTR #define USB_BASE OTG_BASE_ADDR +#define QHARRAY_SIZE ((64*USB_NUM_ENDPOINTS*2 + 2047) & (0xffffffff - 2047)) +#define QHARRAY_PHYS_ADDR ((FRAME_PHYS_ADDR - QHARRAY_SIZE) & (0xffffffff - 2047)) /* * AIPS 1 -- cgit v1.2.3
