board: cssi: Read and display MCR board address

MCR boards are plugged in racks. The position in the rack can be read
in a register.

For MCR3000, that's provided by the FPGA so check it is loaded before
reading the address.

For the other boards, the FPGA is loaded by hardware so it can be
read inconditionnaly.

board: cssi: Load FPGA on MCR3000 board

Unlike CMPC885 and CMPCPRO boards, the FPGA of MCR3000 board doesn't
load code automatically but needs to be loaded by software through SPI.

Until now it was loaded later by Linux, but we'd like U-boot to have
access to some information that require the FPGA, like board address
in racks.

So, implemented the load of FPGA in U-boot.

board: cssi: Add support for SPI bus on MCR3000 board

MCR3000 board has some components tied to the SPI bus, like the Texas
Instruments LM74 temperature sensor.

Add support for SPI bus. The SPI chipselects are a bit special in the
way that they are driven by 3 bits in a register of the board's CPLD
where the value writen in those bits exclusively activates one of the
7 possible chipselects and value 0 sets all chipselets to inactive.

So add a special GPIO driver that simulates GPIOs for those chipselect.

watchdog: mpc8xxx: Make it generic

mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same
memory registers.

Refactor the driver to get the register addresses from the
device tree and use the compatible to know the prescale factor.

Calculate the watchdog setup value from the provided timeout.

Don't declare it anymore as an HW_WATCHDOG, u-boot will start
servicing the watchdog early enough.

On mpc8xx the watchdog configuration register is also used for
configuring the bus monitor. So add it as an option to the watchdog
when it is mpc8xx. When watchdog is not selected, leave the
configuration of the initial SYPCR from Kconfig.

watchdog: mpc8xxx: Make it generic

mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same
memory registers.

Refactor the driver to get the register addresses from the
device tree and use the compatible to know the prescale factor.

Calculate the watchdog setup value from the provided timeout.

Don't declare it anymore as an HW_WATCHDOG, u-boot will start
servicing the watchdog early enough.

On mpc8xx the watchdog configuration register is also used for
configuring the bus monitor. So add it as an option to the watchdog
when it is mpc8xx. When watchdog is not selected, leave the
configuration of the initial SYPCR from Kconfig.

board: cssi: Add support for SPI bus on MCR3000 board

MCR3000 board has some components tied to the SPI bus, like the Texas

Add support for SPI bus. The SPI chipselects are a bit special in the
way that they are driven by 3 bits in a register of the board's CPLD
where the value writen in those bits exclusively activates one of the
7 possible chipselects and value 0 sets all chipselets to inactive.

board: cssi: Read and display MCR board address

MCR boards are plugged in racks. The position in the rack can be read
in a register.

For MCR3000, that's provided by the FPGA so check it is loaded before
reading the address.

For the other boards, the FPGA is loaded by hardware so it can be
read inconditionnaly.

board: cssi: Load FPGA on MCR3000 board

Unlike CMPC885 and CMPCPRO boards, the FPGA of MCR3000 board doesn't
load code automatically but needs to be loaded by software through SPI.

Until now it was loaded later by Linux, but we'd like U-boot to have
access to some information that require the FPGA, like board address
in racks.

So, implemented the load of FPGA in U-boot.

board: cssi: Add support for SPI bus on MCR3000 board

MCR3000 board has some components tied to the SPI bus, like the Texas
Instruments LM74 temperature sensor.

Add support for SPI bus. The SPI chipselects are a bit special in the
way that they are driven by 3 bits in a register of the board's CPLD
where the value writen in those bits exclusively activates one of the
7 possible chipselects and value 0 sets all chipselets to inactive.

So add a special GPIO driver that simulates GPIOs for those chipselect.

watchdog: mpc8xxx: Make it generic

mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same
memory registers.

Refactor the driver to get the register addresses from the
device tree and use the compatible to know the prescale factor.

Calculate the watchdog setup value from the provided timeout.

Don't declare it anymore as an HW_WATCHDOG, u-boot will start
servicing the watchdog early enough.

On mpc8xx the watchdog configuration register is also used for
configuring the bus monitor. So add it as an option to the watchdog
when it is mpc8xx. When watchdog is not selected, leave the
configuration of the initial SYPCR from Kconfig.

watchdog: mpc8xxx: Make it generic

mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same
memory registers.

Refactor the driver to get the register addresses from the
device tree and use the compatible to know the prescale factor.

Calculate the watchdog setup value from the provided timeout.

Don't declare it anymore as an HW_WATCHDOG, u-boot will start
servicing the watchdog early enough.

On mpc8xx the watchdog configuration register is also used for
configuring the bus monitor. So add it as an option to the watchdog
when it is mpc8xx. When watchdog is not selected, leave the
configuration of the initial SYPCR from Kconfig.

MCR boards are plugged in racks. The position in the rack can be read

board: cssi: Load FPGA on MCR3000 board

Unlike CMPC885 and CMPCPRO boards, the FPGA of MCR3000 board doesn't
load code automatically but needs to be loaded by software through SPI.

Until now it was loaded later by Linux, but we'd like U-boot to have
access to some information that require the FPGA, like board address
in racks.

So, implemented the load of FPGA in U-boot.

board: cssi: Add support for SPI bus on MCR3000 board

MCR3000 board has some components tied to the SPI bus, like the Texas
Instruments LM74 temperature sensor.

Add support for SPI bus. The SPI chipselects are a bit special in the
way that they are driven by 3 bits in a register of the board's CPLD
where the value writen in those bits exclusively activates one of the
7 possible chipselects and value 0 sets all chipselets to inactive.

So add a special GPIO driver that simulates GPIOs for those chipselect.

Refactor the driver to get the register addresses from the
device tree and use the compatible to know the prescale factor.

Calculate the watchdog setup value from the provided timeout.

Don't declare it anymore as an HW_WATCHDOG, u-boot will start
servicing the watchdog early enough.

On mpc8xx the watchdog configuration register is also used for
configuring the bus monitor. So add it as an option to the watchdog

board: cssi: Add support for SPI bus on MCR3000 board

MCR3000 board has some components tied to the SPI bus, like the Texas
Instruments LM74 temperature sensor.

Add support for SPI bus. The SPI chipselects are a bit special in the
way that they are driven by 3 bits in a register of the board's CPLD
where the value writen in those bits exclusively activates one of the
7 possible chipselects and value 0 sets all chipselets to inactive.

So add a special GPIO driver that simulates GPIOs for those chipselect.

board: cssi: Remove usage of common.h

Remove inclusion of common.h and add relevant
includes when necessary.

watchdog: mpc8xxx: Make it generic

mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same
memory registers.

Refactor the driver to get the register addresses from the
device tree and use the compatible to know the prescale factor.

Calculate the watchdog setup value from the provided timeout.

Don't declare it anymore as an HW_WATCHDOG, u-boot will start
servicing the watchdog early enough.

On mpc8xx the watchdog configuration register is also used for
configuring the bus monitor. So add it as an option to the watchdog
when it is mpc8xx. When watchdog is not selected, leave the
configuration of the initial SYPCR from Kconfig.

board: MCR3000: Use lowercase filenames

Rename MCR3000.* to mcr3000.* to be more in line with
other boards.

board: cssi: Read and display MCR board address

MCR boards are plugged in racks. The position in the rack can be read
in a register.

For MCR3000, that's provided by the FPGA so check it is loaded before
reading the address.

For the other boards, the FPGA is loaded by hardware so it can be
read inconditionnaly.

board: cssi: Load FPGA on MCR3000 board

Unlike CMPC885 and CMPCPRO boards, the FPGA of MCR3000 board doesn't
load code automatically but needs to be loaded by software through SPI.

Until now it was loaded later by Linux, but we'd like U-boot to have
access to some information that require the FPGA, like board address
in racks.

So, implemented the load of FPGA in U-boot.
