include/linux/byteorder: import latest endian definitions from linux
u-boot's byteorder headers did not contain endianness attributions for use with sparse, causing a lot of false positives. Import the kernel's latest definitions, and enable them by including compiler.h and types.h. They come with 'const' added for some swab functions, so fix those up, too: include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default] Also, note: u-boot's historic __BYTE_ORDER definition has been preserved (for the time being at least). We also remove ad-hoc barrier() definitions, since we're including compiler.h in files that hadn't in the past: macb.c:54:0: warning: "barrier" redefined [enabled by default] In addition, including compiler.h in byteorder changes the 'noinline' definition to expand to __attribute__((noinline)). This fixes arch/powerpc/lib/bootm.c: bootm.c:329:16: error: attribute '__attribute__': unknown attribute bootm.c:329:16: error: expected ')' before '__attribute__' bootm.c:329:25: error: expected identifier or '(' before ')' token powerpc sparse builds yield: include/common.h:356:22: error: marked inline, but without a definition the unknown-reason inlining without a definition is considered obsolete given it was part of the 2002 initial commit, and no arm version was 'fixed.' also fixed: ydirectenv.h:60:0: warning: "inline" redefined [enabled by default] and: Configuring for devconcenter - Board: intip, Options: DEVCONCENTER make[1]: *** [4xx_ibm_ddr2_autocalib.o] Error 1 make: *** [arch/powerpc/cpu/ppc4xx/libppc4xx.o] Error 2 powerpc-fsl-linux-size: './u-boot': No such file 4xx_ibm_ddr2_autocalib.c: In function 'DQS_autocalibration': include/asm/ppc4xx-sdram.h:1407:13: sorry, unimplemented: inlining failed in call to 'ppc4xx_ibm_ddr2_register_dump': function body not available 4xx_ibm_ddr2_autocalib.c:1243:32: sorry, unimplemented: called from here and: In file included from crc32.c:50:0: crc32table.h:4:1: warning: implicit declaration of function '___constant_swab32' [-Wimplicit-function-declaration] crc32table.h:4:1: error: initializer element is not constant crc32table.h:4:1: error: (near initialization for 'crc32table_le[0]') Signed-off-by: Kim Phillips <kim.phillips@freescale.com> [trini: Remove '#endif' in include/common.h around setenv portion] Signed-off-by: Tom Rini <trini@ti.com>
