*	arm: Use optimized memcpy and memset from linux	Matthias Weisser	2011-04-27	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Using optimized versions of memset and memcpy from linux brings a quite noticeable speed (x2 or better) improvement for these two functions. Here are some numbers for test done with jadecpu \| HEAD(1)\| HEAD(1)\| HEAD(2)\| HEAD(2)\| \| \| +patch \| \| +patch \| ---------------------------+--------+--------+--------+--------+ Reset to prompt \| 438ms \| 330ms \| 228ms \| 120ms \| \| \| \| \| \| TFTP a 3MB img \| 4782ms \| 3428ms \| 3245ms \| 2820ms \| \| \| \| \| \| FATLOAD USB a 3MB img* \| 8515ms \| 8510ms \| ------ \| ------ \| \| \| \| \| \| BOOTM LZO img in RAM \| 3473ms \| 3168ms \| 592ms \| 592ms \| where CRC is \| 615ms \| 615ms \| 54ms \| 54ms \| uncompress \| 2460ms \| 2462ms \| 450ms \| 451ms \| final boot_elf \| 376ms \| 68ms \| 65ms \| 65ms \| \| \| \| \| \| BOOTM LZO img in FLASH \| 3207ms \| 2902ms \| 1050ms \| 1050ms \| where CRC is \| 600ms \| 600ms \| 135ms \| 135ms \| uncompress \| 2209ms \| 2211ms \| 828ms \| 828ms \| \| \| \| \| \| Copy 1.4MB from NOR to RAM \| 134ms \| 72ms \| 120ms \| 70ms \| (1) No dcache (2) dcache enabled in board_init *Does not work when dcache is on Size impact: C version: text data bss dec hex filename 202862 18912 266456 488230 77326 u-boot ASM version: text data bss dec hex filename 203798 18912 266288 488998 77626 u-boot 222712 u-boot.bin Signed-off-by: Matthias Weisser <weisserm@arcor.de>
*	Switch from archive libraries to partial linking	Sebastien Carlier	2010-11-17	1	-5/+5
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
*	Move lib_$ARCH directories to arch/$ARCH/lib	Peter Tyser	2010-04-13	1	-0/+82
	Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
