| * cmd/fdt: support single value replacement within an arrayHannes Schmelzer2017-06-091-8/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this commit we can modify single values within an array of a dts property. This is useful if we have for example a pwm-backlight where we want to modifiy the pwm frequency per u-boot script. The pwm is described in dts like this: backlight { pwms = <0x0000002b 0x00000000 0x004c4b40>; }; For changing the frequency, here the 3rd parameter, we simply type: fdt set /backlight pwms <? ? 0x1E8480>; For doing all this we: - backup the property content into our 'SCRATCHPAD' - only modify the array-cell if the new content doesn't start with '?'

| * buildman: properly translate strings for log and err files to ASCIIDaniel Schwierzeck2017-06-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | The build output can still produce unicode encoded output. But in the buildman's log and err files we only want plain ASCII characters. To handle all situations with unicode and non-unicode output, encode the stdout and stderr strings to UTF-8 and afterwards to ASCII with replacing all special characters.

| | | | | | | | | | | | | | | | | | | | Build tools like Make, gcc or binutils support localized output or unicode encoded output dependent on the default system locale. This is not useful for buildman, where we want reproducible warning or error messages or where the output of binutils is further processed.

This avoids leaving DMA running while booting Linux which can cause problems if Linux uses the frame buffer for something else. It also makes it clear what is needed to shut down video.
