* pstore/ram: Clarify resource reservation labelsKees Cook2019-03-181-25/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ramoops reserved a memory region in the kernel, it had an unhelpful label of "persistent ram". When reading iomem, it would be repeated many times, did not hint that it was ramoops in particular, and didn't clarify very much about what each was used for: 0x4fdd4000 - 0x4fdf3fff (size 0x00020000) persistent ram 0x4fdf4000 - 0x4fe13fff (size 0x00020000) persistent ram ... 0x4ff74000 - 0x4ff93fff (size 0x00020000) persistent ram 0x4ff94000 - 0x4ffb3fff (size 0x00020000) persistent ram 0x4ffb4000 - 0x4ffd3fff (size 0x00020000) persistent ram Instead, this adds meaningful labels for how the various regions are being used: 0x4fdd4000 - 0x4fdf3fff (size 0x00020000) ramoops:dump(0/12) 0x4fdf4000 - 0x4fe13fff (size 0x00020000) ramoops:dump(1/12) ... 0x4ff74000 - 0x4ff93fff (size 0x00020000) ramoops:console 0x4ff94000 - 0x4ffb3fff (size 0x00020000) ramoops:ftrace 0x4ffb4000 - 0x4ffd3fff (size 0x00020000) ramoops:pmsg Signed-off-by: Kees Cook <keescook@chromium.org> Reviewed-by: Joel Fernandes (Google) <joel@joelfernandes.org> [p.zabel@pengutronix.de: ported to Barebox from Linux commit 1227daa43bce] Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Documentation: fix code block and literal block highlightingRoland Hieber2018-08-107-8/+22
| | | | | | | | | Use shell script highlighting where it is resonable, use console highlighting for transcripts, and fix some of the few cases where the syntax was broken, resulting in text not being rendered at all.
