2011-03-07fsl_esdhc: Correcting esdhc timeout counter calculationPriyanka Jain1-1/+15
- Timeout counter value is set as DTOCV bits in SYSCTL register For counter value set as timeout, Timeout period = (2^(timeout + 13)) SD Clock cycles - As per 4.6.2.2 section of SD Card specification v2.00, host should cofigure timeout period value to minimum 0.25 sec. - Number of SD Clock cycles for 0.25sec should be minimum (SD Clock/sec * 0.25 sec) SD Clock cycles = (mmc->tran_speed * 1/4) SD Clock cycles - Calculating timeout based on (2^(timeout + 13)) >= mmc->tran_speed * 1/4 Taking log2 both the sides and rounding up to next power of 2 => timeout + 13 = log2(mmc->tran_speed/4) + 1 Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com> Acked-by: Mingkai Hu <Mingkai.Hu@freescale.com> Tested-by: Stefano Babic <sbabic@denx.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-12-18fsl_esdhc: Use mmc_set_clock to set initial speedJerry Huang1-1/+1
After booting the u-boot, and first using some SD card (such as Sandisk 2G SD card), because the field 'clock' of struct mmc is zero, this will cause the read transfer is always active and SDHC DATA line is always active, therefore, driver can't handle the next command. Therefore, we use mmc_set_clock to setup both the data structure and HW to the initial clock speed of 400000Hz.

2010-11-19mmc: omap: timeout counter fixNishanth Menon1-25/+82
Having a loop with a counter is no timing guarentee for timing accuracy or compiler optimizations. For e.g. the same loop counter which runs when the MPU is running at 600MHz will timeout in around half the time when running at 1GHz. or the example where GCC 4.5 compiles with different optimization compared to GCC 4.4. use timer to keep track of time elapse and we use an emperical number - 1sec for a worst case timeout. This should never happen, and is adequate imaginary condition for us to fail with timeout. Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
2010-11-17Switch from archive libraries to partial linkingSebastien Carlier1-2/+2
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>
