Move DECLARE_GLOBAL_DATA_PTR to file scope

2010-12-21T10:33:36+00:00

It can be optimised out by the compiler otherwise resulting
in obscure errors like a board not booting.

This has been documented in README since 2006 when these were
first fixed up for GCC 4.x.

OMAP3: EVM: Convert omap3_evm_version to u32

2010-12-18T22:15:24+00:00

Convert the variable omap3_evm_version to u32 to work around
some broken linkers from older tool chains. E.g. CodeSourcery's
2009q1-203 ld 2.19.51.20090205. Without this, these linkers
stop linking 'omap3_evm' or at least issue a warning. Like

arm-none-linux-gnueabi-ld: section .bss [8003f5e0 -> 8007e337] overlaps section .rel.dyn [8003f5e0 -> 80044e57]
arm-none-linux-gnueabi-ld: section .dynsym [80044e58 -> 80044ef7] overlaps section.bss [8003f5e0 -> 8007e337]
arm-none-linux-gnueabi-ld: u-boot: section .bss vma 0x8003f5e0 overlaps previous sections

fsl_esdhc: Fix the voltage validation process

2010-12-18T22:15:24+00:00

The current code use all the voltage range support by the host
controller to do the validation.  This will cause problem when
the host supports Low Voltage Range.  Change the validation
voltage to be based on board setup.

fsl_esdhc: Use mmc_set_clock to set initial speed

2010-12-18T22:15:21+00:00

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.
