This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board
(This commit was automatically generated by a conversion script
based on boards.cfg)
In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.
But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

Overview -------- P1022ds is a Low End Dual core platform supporting the P1022 processor of QorIQ series. P1022 is an e500 based dual core SOC. Pin Multiplex(hwconfig setting) ------------------------------- Add the environment 'usb2', 'audclk' and 'tdm' to support pin multiplex via hwconfig, i.e: 'setenv hwconfig usb2' to enable USB2 and disable eTsec2 'setenv hwconfig tdm' to enable TDM and disable Audio 'setenv hwconfig audclk:12' to enable Audio(codec clock sources is 12MHz) and disable TDM 'setenv hwconfig 'usb2;tdm' to enable USB2 and TDM, disable eTsec2 and Audio 'setenv hwconfig 'usb2;audclk:11' to enable USB2 and Audio(codec clock sources is 11MHz), disable eTsec2 and TDM Warning: TDM and AUDIO can not enable simultaneous ! and AUDIO codec clock sources only setting as 11MHz or 12MHz ! 'setenv hwconfig 'audclk:12;tdm' --- error ! 'setenv hwconfig 'audclk:11;tdm' --- error ! 'setenv hwconfig 'audclk:10' --- error !
