* ARM: rpi: Clarify debug uart namesSascha Hauer2019-03-071-2/+2
| | | | | | | Now that we support the miniuart as lowlevel debug UART clarify that the other UARTs are PL011. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: rpi: Add mini UART debug_ll supportSascha Hauer2019-03-061-0/+6
| | | | | | | The raspberry pi 3 comes up with the mini UART as default, so allow to use it for debug_ll output. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: rpi: move debug UART Kconfig settingsSascha Hauer2019-03-061-0/+13
| | | | | | | | | | | | In contrast to other architectures, R.Pi debug UART config was placed under the "System Type" menu, not under the "Debugging -> low-level debugging port". This made this setting easy to miss when enabling low level debug mesages. While at it use the existing base address defines rather than defining them again in Kconfig.

| * memory: of_fixup: adapt to new memory layoutMarco Felsch2019-02-121-18/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since kernel 4.16 the memory nodes got a @<reg> suffix so the fixup won't work correctly anymore, because instead of adapting the extisting one the fixup creates a new node and keeps the old (maybe incorrect) node. To be compatible with the old and new layout delete the found memory node and create a new one. The new node follows the new @<reg> style. The patch also renames the node parameter to make it clearer. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * common: state: harmonize code with dt-utilsUlrich Ölmann2019-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux userspace with recent glibc versions lets barebox-state suffer from linux/stat.h redefining 'struct statx' and because of that switched to the inclusion of sys/stat.h instead, see dt-utils commit 1c80e31872ae ("src: fix compilation for glibc version 2.27.9000-36.fc29 and newer"). We can follow this switch in barebox without any problems, too, as in barebox sys/stat.h includes linux/stat.h (and adds some more definitions on top that don't hurt us here).

While there's probably no meaningful way to use lseek() against any of those devices, there doesn't seem to be any harm in allowing it either.
