ARM: imx: enable big endian mode 2016-02-02T05:31:19+00:00 Johannes Berg johannes@sipsolutions.net 2016-01-27T16:59:36+00:00 26e30c6489f4774492c168c7b953e575a16765f7 Enable ARM big-endian mode on mach-imx. This requires adding some byte swapping in the debug functions (which otherwise hang forever) and of course the secondary core bringup. Tested (on top of 4.4) on i.MX6 HummingBoard quad-core (IMX6Q). The patch is pretty much as suggested by Arnd Bergmann, thanks! Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

ARM: imx: support DEBUG_LL uart port selection for all i.MX SoCs 2013-02-05T02:14:55+00:00 Shawn Guo shawn.guo@linaro.org 2012-12-12T11:03:53+00:00 f8c95fe6d9adad72fc7bce90f4ab68d119f50c5b Extend imx6q DEBUG_LL uart port selection support to cover all i.MX SoCs. The 'range' of the Kconfig option gets dropped, as users looking at the option must know the uart number on his board. The bottom line is that the build system will report an error if an invalid port number is picked for given SoC. The header arch/arm/include/debug/imx-uart.h is created to accommodate all the uart base addresses. And the header will also be used for other low-level debug facility later.

ARM: imx6q: let users input debug uart port number 2012-11-16T06:18:52+00:00 Shawn Guo shawn.guo@linaro.org 2012-10-08T05:44:29+00:00 49c9e60eaaa966cdb02ac9e989eeb6f940691c5d imx6q gets 5 uart ports in total. Different board design may choose different port as debug uart. For example, imx6q-sabresd uses UART1, imx6q-sabrelite uses UART2 and imx6q-arm2 uses UART4. Rather than bloating DEBUG_LL choice list with all these uart ports, the patch introduces DEBUG_IMX6Q_UART_PORT for users to input uart port number when DEBUG_IMX6Q_UART is selected inside DEBUG_LL choice.

It removes the inclusion to hardware.h by hard-coding the physical address of uart port and copying IMX_IO_P2V from hardware.h. Since we will need a common solution, which might use a fixed virtual address for uart port across platforms, we make a copy of IMX_IO_P2V here as a temporary solution to enable low-level debug for imx multi-platform build.
