	This patch adds a new pstore command allowing to display or save ramoops logs (oops, panic, console, ftrace and user) generated by a previous kernel crash. PStore parameters can be set in U-Boot configuration file, or at run-time using "pstore set" command. Records size should be the same as the ones used by kernel, and should be a power of 2. This command allows: - to display uncompressed logs - to save compressed or uncompressed logs, compressed logs are saved as a compressed stream, it may need some work to be able to decompress it, e.g. adding a fake header: "printf "\x1f\x8b\x08\x00\x00\x00\x00\x00\x00\x00" | cat - dmesg-ramoops-0.enc.z | gzip -dc" - ECC part is not used to check memory corruption - only 1st FTrace log is displayed or saved Signed-off-by: Frédéric Danis <frederic.danis@collabora.com> [trini: Minor updates for current design, correct spacing in rST] Signed-off-by: Tom Rini <trini@konsulko.com> Cc: Heinrich Schuchardt <xypron.glpk@gmx.de> Cc: Wolfgang Denk <wd@denx.de> Cc: Heiko Schocher <hs@denx.de>

| The U-Boot Documentation
 | |
| ========================
 | |
| 
 | |
| This is the top level of the U-Boot's documentation tree.  U-Boot
 | |
| documentation, like the U-Boot itself, is very much a work in progress;
 | |
| that is especially true as we work to integrate our many scattered
 | |
| documents into a coherent whole.  Please note that improvements to the
 | |
| documentation are welcome; join the U-Boot list at http://lists.denx.de
 | |
| if you want to help out.

| User-oriented documentation
 | |
| ---------------------------
 | |
| 
 | |
| The following manuals are written for *users* of the U-Boot - those who are
 | |
| trying to get it to work optimally on a given system.

| Developer-oriented documentation
 | |
| --------------------------------
 | |

| The following manuals are written for *developers* of the U-Boot - those who
 | |
| want to contribute to U-Boot.

| Unified Extensible Firmware (UEFI)
 | |
| ----------------------------------
 | |
| 
 | |
| U-Boot provides an implementation of the UEFI API allowing to run UEFI
 | |
| compliant software like Linux, GRUB, and iPXE. Furthermore U-Boot itself
 | |
| can be run an UEFI payload.

| Driver-Model documentation
 | |
| --------------------------
 | |
| 
 | |
| The following holds information on the U-Boot device driver framework:
 | |
| driver-model, including the design details of itself and several driver
 | |
| subsystems.

| U-Boot API documentation
 | |
| ------------------------
 | |
| 
 | |
| These books get into the details of how specific U-Boot subsystems work
 | |
| from the point of view of a U-Boot developer.  Much of the information here
 | |
| is taken directly from the U-Boot source, with supplemental material added
 | |
| as needed (or at least as we managed to add it - probably *not* all that is
 | |
| needed).
