From bea2868f5e5f994db3f6cf23a6111cfd6ac79fc3 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Sun, 26 May 2013 12:11:26 +0200 Subject: nds32: introduce macros for bit manipulation U-Boot does not compile for the adp-ag101 boards since commit f6c3b34697bf8bf05cb4e81c2fd3cadb9a98daea (mmc: update Faraday FTSDC010 for rw performance) The driver assumes that the bit manipulation macros are provided by all architectures. This is not the case for nds32 and it causes a build error like this: ftsdc010_mci.c: In function 'ftsdc010_clkset': ftsdc010_mci.c:118: warning: implicit declaration of function 'setbits_le32' ftsdc010_mci.c:123: warning: implicit declaration of function 'clrbits_le32' drivers/mmc/libmmc.o: In function `ftsdc010_request': /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:234: undefined reference to `setbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:243: undefined reference to `clrbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:234: undefined reference to `clrbits_le32' drivers/mmc/libmmc.o: In function `ftsdc010_clkset': /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:118: undefined reference to `clrbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:118: undefined reference to `clrbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:121: undefined reference to `setbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:123: undefined reference to `setbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:123: undefined reference to `setbits_le32' The patch adds bit manipulation macros for the nds32 architecture to avoid the errors. The macros are copied from the ARM implementation. Compile tested only.

However the actual driver code unconditionally uses the FTSDC010_DCR_FIFO_RST constant and this causes build error if CONFIG_FTSDC010_SDIO is not enabled. The following error happens when compiling for the adp-ag101 board: ftsdc010_mci.c: In function 'ftsdc010_request': ftsdc010_mci.c:178: error: 'FTSDC010_DCR_FIFO_RST' undeclared (first use in this function) ftsdc010_mci.c:178: error: (Each undeclared identifier is reported only once ftsdc010_mci.c:178: error: for each function it appears in.) The patch ensures that the FTSDC010_DCR_FIFO_RST symbol gets used only if CONFIG_FTSDC010_SDIO is defined. Compile tested only.

The unit of "readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2)" is second. However, CONFIG_SYS_HZ is defined as 1000 in board config file. This means the accuracy of "lastdec" and "now" should be in millisecond, thus fix the equation to set lastdec and now variables accordingly.
