2014-02-03kmp204x: initial support for PCIe FPGA configurationValentin Longchamp
The PEXHC PCIe configuration mechanism ensures that the FPGA get configured at power-up. Since all the PCIe devices should be configured when the kernel start, u-boot has to take care that the FPGA gets configured also in other reset scenarios, mostly because of possible configuration change. The used mechanism is taken from the km_kirkwood design and adapted to the kmp204x case (slightly different HW and PCIe configuration).

2014-02-03kmp204x: update I2C field of RCWValentin Longchamp
On the previous HW revision (now unsupported), there was a need for external DMA signals and thus the I2C3/4 signals were used DMA1_DONE/ACK/REQ. These signals now are configured as GPIO[16:19].

2014-02-03kmp204x: implement workaround for A-006559Valentin Longchamp
According to the errata, some bits of an undocumented register in the DCSR must be set for every core in order to avoid a possible data or instruction corruption. This is required for the 2.0 revision of the P2041 that should be used as soon as available in our design.

2014-02-03kmp204x: I2C deblocking supportRainer Boschung
This patch adds support for using some GPIOs that are connected to the I2C bus to force the bus lines state and perform some bus deblocking sequences. The KM common deblocking algorithm from board/keymile/common/common.c is used. The GPIO lines used for deblocking the I2C bus are some external GPIOs provided by the QRIO CPLD: - SCL = GPIOA_20 - SDA = GPIOA_21 The QRIO GPIOs act in an open-drain-like manner, for 0 the line is driven low and for 1 the GPIO is set as input and the line gets pulled-up.

2013-10-24mpc85xx: introduce the kmp204x reference design supportValentin Longchamp
This patch introduces the support for Keymile's kmp204x reference design. This design is based on Freescale's P2040/P2041 SoC. The peripherals used by this design are: - DDR3 RAM with SPD support - SPI NOR Flash as boot medium - NAND Flash - 2 PCIe busses (hosts 1 and 3) - 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5) - 3 Local Bus windows, with one dedicated to the QRIO reset/power mgmt FPGA - 2 HW I2C busses - last but not least, the mandatory serial port The board/keymile/kmp204x code is mostly based on Freescale's P2041rdb support and was changed according to our design (that means essentially removing what is not present on the designs and a few adaptations). There is currently only one prototype board that is based on this design and this patch also introduces it. The board is called kmlion1.

This must be defined by a board support file that want to use the keymile common.c board_eth_init function that requires ethernet_present to be defined. Currently all the km architectures use it but the kmp204x architecture later supported in this series does use another board_eth_init function and thus does not define it.

The ethernet port used for network booting is automatically selected by u-boot. If a Piggy is plugged, the Piggy port is selected (UEC2, eth1). If the Piggy isn't present, the Frontport is selected (UEC0, eth0). The switch reset is connected to a GPIO on the PRIO3 board FPGA (GPIO28) and released at startup.

2013-01-09arm/km: remove duplicate codeValentin Longchamp
This patch removes 2 small portions of board specific code that are duplicated with common ARM code and thus unnecessary. These 2 portions of code concern the mach id that is given by u-boot to the Linux kernel to identify the system's MACH. The first one was the possibility to change the MACH thanks to the 'mach_id' enviroment variable. This is possible thanks to the 'machid' env variable (see arch/arm/lib/bootm.c:boot_jump_linux()). The seconde one is the setting of the bi_arch_number. This is already done in arch/arm/lib/board.c:board_init_f() since km_arm.h does #define CONFIG_MACH_TYPE.
