[U-Boot-Users] [PATCH] Allow negative offset in command loads

[U-Boot-Users] [PATCH] Allow negative offset in command loads

[Ricardo Ribalda Delgado]

Comand loads only allows positive offset for relocating the .srec files,
this patch allows negative offsets

[U-Boot-Users] [PATCH] I2C EEPROM simulator (Resubmit)

[Ricardo Ribalda Delgado]

This driver provides access to a simulated i2c eeprom.
This simulated eeprom could be very useful in boards with
ddr2 memories and no i2c interfaces.

Using this driver the user can simulate a spd eeprom
of a ddr2 memory and use the ddr2 auto config.

User can use the macros CONFIG_EEPROM_SIMUL_LEN
and CONFIG_EEPROM_SIMUL_DATA to define the content
of the simulated eeprom
