| * | | | imx:mx6 fix return value of mxc_get_clockPeng Fan2014-12-19-1/+2
| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mxc_get_clock's return type is unsigned int. 'return -1' is same with 'return 0xffffffff', so 0 should be used as the return value when unsupported mxc_clock type is passed to mxc_get_clock. Also include an err message when unsupported mxc_clock type is passed to mxc_get_clock. Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Reviewed-by: Fabio Estevam <fabio.estevam@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By rearranging the functions in the semihosting code we can avoid forward-declaration of the internal static functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is currently a regression when using newer ARM64 compilers for semihosting: the way long types are inferred from context is no longer the same. The semihosting runtime uses long and size_t, so use this explicitly in the semihosting code and interface, and voila: the code now works again. Tested with aarch64-linux-gnu-gcc: Linaro GCC 4.9-2014.09.

However the code using it is only interested in either reading and entire named file into memory or getting the file length of a file referred by name. No file handles are used. Thus make the file handle code internal to this file by removing these functions from the semihosting header file and staticize them. This gives us some freedom to rearrange the semihosting code without affecting the external interface.

The first one is the TempRamInit (aka Cache-As-Ram initialization) and the second one is the FspInit which does the memory bring up (like MRC for other x86 targets) and chipset initialization. Those two routines have to be called before U-Boot jumping to board_init_f in start.S. The FspInit() will return several memory blocks called Hand Off Blocks (HOBs) whose format is described in Platform Initialization (PI) specification (part of the UEFI specication) to the bootloader.
