From a89dd2ca6542d157890656d918d6ae2f933ab401 Mon Sep 17 00:00:00 2001 From: oharboe Date: Thu, 3 Sep 2009 08:23:39 +0000 Subject: David Brownell Abstract the orion_nand_fast_block_write() routine into a separate routine -- arm_nandwrite() -- so that other ARM cores can reuse it. Have davinci_nand do so. This faster than byte-at-a-time ops by a factor of three (!), even given the slowish interactions to support hardware ECC (1-bit flavor in that test) each 512 bytes; those could be read more efficiently by on-chip code. NOTE that until there's a generic "ARM algorithm" structure, this can't work on newer ARMv6 (like ARM1136) or ARMv7A (like Cortex-A8) cores, though the downloaded code itself would work just fine there. git-svn-id: svn://svn.berlios.de/openocd/trunk@2663 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- src/flash/nand.h | 1 + 1 file changed, 1 insertion(+) (limited to 'src/flash/nand.h') diff --git a/src/flash/nand.h b/src/flash/nand.h index ab87123d..b73e3304 100644 --- a/src/flash/nand.h +++ b/src/flash/nand.h @@ -223,5 +223,6 @@ extern int nand_init(struct command_context_s *cmd_ctx); #define ERROR_NAND_OPERATION_NOT_SUPPORTED (-1103) #define ERROR_NAND_DEVICE_NOT_PROBED (-1104) #define ERROR_NAND_ERROR_CORRECTION_FAILED (-1105) +#define ERROR_NAND_NO_BUFFER (-1106) #endif /* NAND_H */ -- cgit v1.2.3
