* g: add ITE EC flash programming capabilityVadim Bendebury2018-11-053-0/+285
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a callback function which triggers generation of the ITE EC programming sequence by the H1. It is going to be the board's code responsibility to configure ITE SYNC mode at startup and then reset the H1. The expectation is that when booting after reset the ITE SYNC sequence would be generated before clock jitter is configured and locked. ITE SYNC is a mode when soon after EC reset for duration of at least 20 ms the I2C master generates 200 KHz clock of the SDA line and 100 KHz clock on the SCL line, locked in phase, with 10% frequency variation tolerance. To be able to generate a stable 200 KHz clock jitter has to be disabled, and the actual clock generation function needs to be written in assembler, as this allows for the most accurate clock frequency tuning. The H1 GPIO controller allows to set multiple GPIO pins to requested values in one 32 bit transaction. The C function maps I2C interface directly to the GPIOs, prepares the address of the register to use to control the GPIOs and the values to write to generate all four combinations of the two signals: 00, 01, 10, 11. Then it invokes the assembler function to actually generate the clocks, and then re-enables the clock jitter.

| | | | | | | | | | | | | | | | | | | | | | | | We never need to have interrupts enabled on both SPI1_NSS and EMMC_CMD, so we can actually share the interrupt selection EXTI15 between the 2 pins.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This CL fixed the following bugs of low voltage support of GPIO: 1. fix the mismatch issue of low voltage support GPIOs when the mask passed to gpio_low_voltage_level_sel() has multiple bits set. (see more detail in the bug:118443060.) The idea is to create a new function gpio_low_vol_sel_by_mask() to iterate the match for each bit set in the mask. i.e. while (lv_mask) { bit = get_next_bit(&lv_mask); gpio_low_voltage_level_sel(p, bit, low_vol); }; The second parameter of gpio_match()/gpio_low_voltage_level_sel is also changed from "mask" to "bit" because of above modification. 2. It was observed that there are some errors of the low level mapping table because the older datasheet we used to develop the driver is not correct. After checking the latest datasheets of all EC sku, the low level table should have the following modification: - GPIO65 cannot support low level and should be removed. - GPIO86 can support low level in all EC skus.

* g: allow i2cm transactions of arbitrary lengthVadim Bendebury2018-10-161-131/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Programming ITE EC over CCD is a very tedious process, with a huge overhead imposed by encapsulating I2C traffic in USB packets. On top of that actual writing into the flash must happen in a single transaction passing a full flash page (256 bytes) worth of data. To accommodate this the I2C master driver needs to be modified to send I2C transactions longer than the I2C controller's FIFO capacity of 64 bytes. This patch makes necessary changes and simplifies the driver, even if making it a little less efficient: the modified driver does not use the FW block of the controller, which allowed to program up to for bytes to transmit before actually getting to transmit from or receive to the FIFO. All transfers now involve FIFO and there is always a full stop/start between a write and the following read, as opposed to a single restart issued before in case the write was 4 bytes or less.

* npcx: Decide erase size based on ro/rw region sizeFurquan Shaikh2018-09-055-10/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change updates the erase operation in npcx chip to use 64k/32k/4k block erase depending upon the alignment of CONFIG_RO_SIZE. This helps reduce the EC SW sync time from ~9.5 seconds to ~5.4 seconds on NPCX7. Ideally, we would want to check the offset and size of region to be erased dynamically and decide which erase operation to use. However, common flash code checks against CONFIG_FLASH_ERASE_SIZE to ensure that the area being erased is aligned to that size. Thus, even if we add dynamic erase at chip level, it isn't going to help. This change also updates CONFIG_FLASH_BANK_SIZE to be the same as CONFIG_FLASH_ERASE_SIZE since it is checked by common code. I am honestly not sure why the CONFIG_FLASH_BANK_SIZE is tightly coupled with CONFIG_FLASH_ERASE_SIZE. But, based on the usage, it seems to be a safe change. On the other hand, changing CONFIG_FLASH_BANK_SIZE helps reduce the write time as well, thus overall helping with the EC SW Sync time. Please see go/cros-npcx7-ec-sw-sync for more details.
