[U-Boot] [PATCH v3 0/5] da850evm: add board specific functions

[U-Boot] [PATCH v3 0/5] da850evm: add board specific functions

[manjunath.hadli at ti.com]

From: Manjunath Hadli <manjunath.hadli@ti.com>

There are two boards AM18x and L138 both of which are based
on da850 SOC. AM18x boards have mac address stored in I2C
EEPROM and they have spi flash manufactured by WINBOND. L138
boards store mac address in SPI flash and they have SPI flash
manufactured by ST Microelectronics.Due to these differences,
instead of one config file, two config files are introduced
to manage configs specific to board types.

Changes from previous revision v2:
 1. Changed "da850" to "da850evm" in cover letter and subsequent
    patches.
 2. Dropped cache disabling patch as suggested by Laurence

Manjunath Hadli (5):
  da850evm: add new config file for AM18x
  da850evm: rename config file to represent OMAP-L138
  da850evm: pass board revision info to kernel
  da850evm: add support to read mac address from spi flash
  da850evm: read MAC address from I2C EEPROM on AM18x EVM

[U-Boot] [PATCH v3 1/5] da850evm: add new config file for AM18x

[manjunath.hadli at ti.com]

From: Manjunath Hadli <manjunath.hadli@ti.com>

add new configuration file da850_am18xevm.h for AM18x boards
which are based on da850 SOC. AM18x has WINBOND spi flash which
is indicated in the config file. And make appropriate changes in
board.cfg for building.

[U-Boot] [PATCH v3 2/5] da850evm: rename config file to represent OMAP-L138

[manjunath.hadli at ti.com]

From: Manjunath Hadli <manjunath.hadli@ti.com>

rename config file da850evm.h as da850_l138evm.h to represent omap
l138 board based on da850 SOC. L138 boards dont have WINBOND SPI
flash, corresponding config is removed. Appropriate changes are made
in boards.cfg for building.

Sorry for the late reply.  I see that in the new config all of the
CONFIG_SPI and related options still exist.  Please update, thanks.

[U-Boot] [PATCH v3 3/5] da850evm: pass board revision info to kernel

[manjunath.hadli at ti.com]

From: Manjunath Hadli <manjunath.hadli@ti.com>

there are two boards based on da850 SOC - OMAP-L138 and AM18x.
In order to differentiate between these two boards, revision id
is passed to kernel via second byte of ATAG_REVISION.

[U-Boot] [PATCH v3 4/5] da850evm: add support to read mac address from spi flash

[manjunath.hadli at ti.com]

From: Manjunath Hadli <manjunath.hadli@ti.com>

add support to read mac address from spi flash if env variable
is not set. This is supported only on L138 boards based on da850
SOC. Introduced a macro CONFIG_MAC_ADDR_IN_SPIFLASH indicating
where to look mac address for.

[U-Boot] [PATCH v3 5/5] da850evm: read MAC address from I2C EEPROM on AM18x EVM

[manjunath.hadli at ti.com]

From: Manjunath Hadli <manjunath.hadli@ti.com>

The AM18x EVM contains MAC address in I2C EEPROM. Introduced
a new macro CONFIG_MAC_ADDR_IN_EEPROM to where to look for mac
address. This patch reads MAC address from I2C EEPROM and updates
environment variable.
