* cros_ec: Implement I2C pass-throughSimon Glass2014-03-17-2/+268
| | | | | | | | | The Chrome EC has a feature where you can access its I2C buses through a pass-through arrangement. Add a command to support this, and export the function for it also. Reviewed-by: Vadim Bendebury <vbendeb@google.com> Signed-off-by: Simon Glass <sjg@chromium.org>
* cros_ec: sandbox: Add Chrome OS EC emulationSimon Glass2014-03-17-0/+576
| | | | | | | | Add a simple emulation of the Chrome OS EC for sandbox, so that it can perform various EC tasks such as keyboard handling. Reviewed-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
* cros_ec: Correct comparison between signed and unsigned numbersSimon Glass2014-03-17-16/+18
| | | | | | | | | | | | | | | | | | | | | Due to signed/unsigned comparison, '< sizeof(struct)' does not do the right thing, since if ec_command() returns a -ve number we will consider this be success. Adjust all comparisons to avoid this problem. This error was found with sandbox, which gives a segfault in this case. On ARM we may instead silently fail. We should also consider turning on -Wsign-compare to catch this sort of thing in future.

* cros_ec: Clean up multiple EC protocol supportRandall Spangler2014-03-17-44/+47
| | | | | | | | | | | | | | | Version 1 protocols (without command version) were already no longer supported in cros_ec.c. This removes some dead code from the cros_ec_i2c driver. Version 2 protcols (with command version) are now called protocol_version=2, instead of cmd_version_is_supported=1. A subsequent change will introduce protocol version 3 for SPI.

* x86: Add CBMEM console driver for corebootVadim Bendebury2012-11-30-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch builds upon the recently introduced CBMEM console feature of coreboot. CBMEM console uses a memry area allocated by coreboot to store the console output. The memory area has a certain structure, which allows to determine where the buffer is, the buffer size and the location of the pointer in the buffer. This allows different phases of the firmware (rom based coreboot, ram based coreboot, u-boot after relocation with this change) to keep adding text to the same buffer. Note that this patch introduces a new console driver and adds the driver to the list of drivers to be used for console output, i.e. it engages only after u-boot relocates. Usiong CBMEM console for capturing the pre-relocation console output will be done under a separate change. >From Linux, run the cbmem.py utility (which is a part of the coreboot package) to see the output, e.g.: vvvvvvvvvvvvvvvvv SCSI: AHCI 0001.0300 32 slots 6 ports ?

Magic signature found Kernel command line: "cros_secure quiet loglevel=1 console=tty2... ^^^^^^^^^^^^^^^^^ Note that the entire u-boot output fits into the buffer only if the coreboot log level is reduced from the most verbose.

This is a first of a series of patches - in the future "pmic" will be replaced with "power". Two important issues: 1. The PMIC needs to be initialized just after malloc is configured 2.

* powerpc/corenet_ds: Slave module for boot from PCIELiu Gang2012-08-23-6/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When boot from PCIE, slave's core should be in holdoff after powered on for some specific requirements. Master will release the slave's core at the right time by PCIE interface. Slave's ucode and ENV can be stored in master's memory space, then slave can fetch them through PCIE interface. For the corenet platform, ucode is for Fman. NOTE: Because the slave can not erase, write master's NOR flash by PCIE interface, so it can not modify the ENV parameters stored in master's NOR flash using "saveenv" or other commands. environment and requirement: master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image is in master NOR flash. 3. Put the slave's ucode and ENV into it's own memory space. 4. Normally boot from local NOR flash. 5. Configure PCIE system if needed. slave: 1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV. 2. Boot location should be set to one PCIE interface by RCW. 3. RCW should configure the SerDes, PCIE interfaces correctly. 4. Must set all the cores in holdoff by RCW. 5. Must be powered on before master's boot. For the slave module, need to finish these processes: 1. Set the boot location to one PCIE interface by RCW. 2. Set a specific TLB entry for the boot process. 3. Set a LAW entry with the TargetID of one PCIE for the boot. 4. Set a specific TLB entry in order to fetch ucode and ENV from master. 5. Set a LAW entry with the TargetID one of the PCIE ports for ucode and ENV. 6. Slave's u-boot image should be generated specifically by make xxxx_SRIO_PCIE_BOOT_config. This will set SYS_TEXT_BASE=0xFFF80000 and other configurations. In addition, the processes are very similar between boot from SRIO and boot from PCIE. Some configurations like the address spaces can be set to the same. So the module of boot from PCIE was added based on the existing module of boot from SRIO, and the following changes were needed: 1. Updated the README.srio-boot-corenet to add descriptions about boot from PCIE, and change the name to README.srio-pcie-boot-corenet. 2. Changed the compile config "xxxx_SRIOBOOT_SLAVE" to "xxxx_SRIO_PCIE_BOOT", and the image builded with "xxxx_SRIO_PCIE_BOOT" can support both the boot from SRIO and from PCIE. 3. Updated other macros and documents if needed to add information about boot from PCIE. Signed-off-by: Liu Gang <Gang.Liu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
* powerpc/corenet_ds: Get rid of the CONFIG_SRIOBOOT_SLAVE_PORTx macroLiu Gang2012-08-23-0/+27
| | | | | | | | | | | | | | | | When compile the slave image for boot from SRIO, no longer need to specify which SRIO port it will boot from. The code will get this information from RCW and then finishes corresponding configurations. This has the following advantages: 1. No longer need to rebuild an image when change the SRIO port for boot from SRIO, just rewrite the new RCW with selected port, then the code will get the port information by reading new RCW. 2. It will be easier to support other boot location options, for example, boot from PCIE. Signed-off-by: Liu Gang <Gang.Liu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
