* | spl: Lightweight UBI and UBI fastmap supportThomas Gleixner2016-07-22-0/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the help message of CONFIG_BOOTDELAY says, CONFIG_BOOTDELAY=-2 means the autoboot with no delay, with no abort check even if CONFIG_ZERO_BOOTDELAY_CHECK is defined. To sum up, the autoboot behaves as follows: [1] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=y autoboot with no delay, but you can abort it by key input [2] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n autoboot with no delay, with no check for abort [3] CONFIG_BOOTDELAY=-1 disable autoboot [4] CONFIG_BOOTDELAY=-2 autoboot with no delay, with no check for abort As you notice, [2] and [4] come to the same result, which means we do not need CONFIG_ZERO_BOOTDELAY_CHECK. We can control all the cases only by CONFIG_BOOTDELAY, like this: [1] CONFIG_BOOTDELAY=0 autoboot with no delay, but you can abort it by key input [2] CONFIG_BOOTDELAY=-1 disable autoboot [3] CONFIG_BOOTDELAY=-2 autoboot with no delay, with no check for abort This commit converts the logic as follow: CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n --> CONFIG_BOOTDELAY=-2 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Stefan Roese <sr@denx.de> Acked-by: Igor Grinberg <grinberg@compulab.co.il> Reviewed-by: Simon Glass <sjg@chromium.org> Acked-by: Vladimir Zapolskiy <vz@mleia.com> Reviewed-by: Heiko Schocher <hs@denx.de> Acked-by: Christian Riesch <christian.riesch@omicronenergy.com> Acked-by: Hannes Schmelzer <hannes.schmelzer@br-automation.com>

The intend is for boards which include this file to select this from their Kconfig files and when moving setting to Kconfig which are #define-ed in config_distro_defaults.h to select this from DISTRO_DEFAULTS so that boards which have selected DISTRO_DEFAULTS will keep the same configuration as before without needing any defconfig file changes. The initial list of selected things matches all settings recently removed from config_distro_defaults.h because they have been converted to Kconfig, with the exception of CMD_ELF and CMD_NET, which have a default of y, if the default of these ever changes they should be selected by DISTRO_DEFAULTS too. For testing and example purposes this commit also converts ARCH_SUNXI to use DISTRO_DEFAULT instead of selecting everything it needs itself. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
