The uclass implements the same operations as the current I2C framework but makes some changes to make it fit driver model better: - Remove the chip address from API calls - Remove the address length from API calls - Remove concept of 'current' I2C bus - Drop all existing init functions Acked-by: Heiko Schocher <hs@denx.de> Reviewed-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Simon Glass <sjg@chromium.org>
Entering the maximum number of characters defined by CONFIG_SYS_CBSIZE into the console and hitting enter afterwards, causes a hang in the system because CONFIG_SYS_PBSIZE is not capable of storing the characters of the error message: "Unknown command '' - try 'help'". Provide a default size for CONFIG_SYS_PBSIZE so that it can store the error message and allows the error message to be printed correctly with no hang.

CONFIG_SYS_HZ is always defined as 1000 in config_fallbacks.h (but some boards still have redundant definitions). This commit moves the definition and the document in README to Kconfig. Since lib/Kconfig can assure that CONFIG_SYS_HZ is 1000, the sanity check in lib/time.c should be removed.

make the use of legacy image format configurable through the config define CONFIG_IMAGE_FORMAT_LEGACY. When relying on signed FIT images with required signature check the legacy image format should be disabled. Therefore introduce this new define and enable legacy image format if CONFIG_FIT_SIGNATURE is not set. If CONFIG_FIT_SIGNATURE is set disable per default the legacy image format.

When both CONFIG_API and CONFIG_LCD are enabled, the API code calls lcd_display_bitmap(). That isn't compiled unless either CONFIG_CMD_BMP or CONFIG_SPLASH_SCREEN is enabled. In order to prevent build problems, have config_fallbacks.h enable CONFIG_CMD_BMP when both API and LCD are enabled.

Those commands basis on implementation of random UUID generator version 4
which is described in RFC4122. The same algorithm is used for generation
both ids but string representation is different as below.
char: 0 9 14 19 24 36
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
UUID: be be be be be
GUID: le le le be be
Commands usage:
- uuid [<varname>]
- guid [<varname>]
The result is saved in environment as a "varname" variable if argument is given,
if not then it is printed.
New config:
- CONFIG_CMD_UUID

This patch adds support to generate UUID (Universally Unique Identifier) in version 4 based on RFC4122, which is randomly. Source: https://www.ietf.org/rfc/rfc4122.txt Changes: - new configs: - CONFIG_LIB_UUID for compile lib/uuid.c - CONFIG_RANDOM_UUID for functions gen_rand_uuid() and gen_rand_uuid_str() - add configs dependency to include/config_fallbacks.h for lib uuid. lib/uuid.c: - add gen_rand_uuid() - this function writes 16 bytes len binary representation of UUID v4 to the memory at given address. - add gen_rand_uuid_str() - this function writes 37 bytes len hexadecimal ASCII string representation of UUID v4 to the memory at given address.

Provide a way to use any host file or device as a block device in U-Boot. This can be used to provide filesystem access within U-Boot to an ext2 image file on the host, for example. The support is plumbed into the filesystem and partition interfaces. We don't want to print a message in the driver every time we find a missing device. Pass the information back to the caller where a message can be printed if desired.

According to the README, CONFIG_SYS_HZ must be 1000 and most platforms follow that. In preparation to remove CONFIG_SYS_HZ from all these platforms, provide a common definition.
