* 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nyan-big is a Tegra124 clamshell board that is very similar to venice2, but it has a different panel, the sdcard cd and wp sense are flipped, and it has a different revision of the AS3722 PMIC. This is the Acer Chromebook 13 CB5-311-T7NN (13.3-inch HD, NVIDIA Tegra K1, 2GB). The display is not currently supported, so it should boot on other nyan-based Chromebooks also, but only the device tree for nyan-big is provided here. The device tree file is from Linux but with features removed which are unlikely to be supported in U-Boot soon (regulators, pinmux). Also the addresses are updated to 32-bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some UniPhier boards are equipped with an expansion slot that some optional SRAM/NOR-flash cards can be attached to. So, run-time detection of the number of flash banks would be more user-friendly. Until this commit, UniPhier boards have achieved this by (ab)using board_flash_wp_on() because the boot failed if flash_size got zero. Fortunately, this problem was solved by commit 70879a92561a (flash: do not fail even if flash_size is zero). Now it is possible to throw away such a tricky workaround. This commit also enables CONFIG_SYS_MAX_FLASH_BANKS_DETECT for further refactoring. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
