* | spl: Lightweight UBI and UBI fastmap supportThomas Gleixner2016-07-22-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Booting a payload out of NAND FLASH from the SPL is a crux today, as it requires hard partioned FLASH. Not a brilliant idea with the reliability of todays NAND FLASH chips. The upstream UBI + UBI fastmap implementation which is about to brought to u-boot is too heavy weight for SPLs as it provides way more functionality than needed for a SPL and does not even fit into the restricted SPL areas which are loaded from the SoC boot ROM. So this provides a fast and lightweight implementation of UBI scanning and UBI fastmap attach. The scan and logical to physical block mapping code is developed from scratch, while the fastmap implementation is lifted from the linux kernel source and stripped down to fit the SPL needs. The text foot print on the board which I used for development is: 6854 0 0 6854 1abd drivers/mtd/ubispl/built-in.o Attaching a NAND chip with 4096 physical eraseblocks (4 blocks are reserved for the SPL) takes: In full scan mode: 1172ms In fastmap mode: 95ms The code requires quite some storage. The largest and unknown part of it is the number of fastmap blocks to read. Therefor the data structure is not put into the BSS. The code requires a pointer to free memory handed in which is initialized by the UBI attach code itself. See doc/README.ubispl for further information on how to use it. This shares the ubi-media.h and crc32 implementation of drivers/mtd/ubi There is no way to share the fastmap code, as UBISPL only utilizes the slightly modified functions ubi_attach_fastmap() and ubi_scan_fastmap() from the original kernel ubi fastmap implementation.

| | | | | | | | | | | | | | | | At present CONFIG_SKIP_LOWLEVEL_INIT prevents U-Boot from calling lowlevel_init(). This means that the instruction cache is not enabled and the board runs very slowly. What is really needed in many cases is to skip the call to lowlevel_init() but still perform CP15 init. Add an option to handle this.

* cmd: eeprom: add support for layout aware commandsNikita Kiryanov2016-05-20-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce the (optional) eeprom print and eeprom update commands. These commands are eeprom layout aware: * The eeprom print command prints the contents of the eeprom in a human readable way (eeprom layout fields, and data formatted to be fit for human consumption). * The eeprom update command allows user to update eeprom fields by specifying the field name, and providing the new data in a human readable format (same format as displayed by the eeprom print command). * Both commands can either auto detect the layout, or be told which layout to use. New CONFIG options: CONFIG_CMD_EEPROM_LAYOUT - enables commands. CONFIG_EEPROM_LAYOUT_HELP_STRING - tells user what layout names are supported Feature API: __weak int parse_layout_version(char *str) - override to provide your own layout name parsing __weak void __eeprom_layout_assign(struct eeprom_layout *layout, int layout_version); - override to setup the layout metadata based on the version __weak int eeprom_layout_detect(unsigned char *data) - override to provide your own algorithm for detecting layout version eeprom_field.c - contains various printing and updating functions for common types of eeprom fields. Can be used for defining custom layouts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are already two FIT options in Kconfig but the CONFIG options are still in the header files. We need to do a proper move to fix this. Move these options to Kconfig and tidy up board configuration: CONFIG_FIT CONFIG_OF_BOARD_SETUP CONFIG_OF_SYSTEM_SETUP CONFIG_FIT_SIGNATURE CONFIG_FIT_BEST_MATCH CONFIG_FIT_VERBOSE CONFIG_OF_STDOUT_VIA_ALIAS CONFIG_RSA Unfortunately the first one is a little complicated. We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file. To solve this, add a new IMAGE_USE_FIT #define which can be used in files that are built on the host but must also build for U-Boot and SPL. Note: Masahiro's moveconfig.py script is amazing.

Unfortunately, it is global to all protocols, and the value is interpreted differently in all of them. Add a new environment variable that directly sets the retry period for BOOTP timeouts. If this new value is not set, the period is still derived from the default number of retries, or from CONFIG_NET_RETRY_COUNT if defined. When both the new variable is set and CONFIG_NET_RETRY_COUNT is defined, the variable has precedence. Signed-off-by: Alexandre Messier <amessier@tycoint.com>
