| | | * | designware_i2c: Fixed the setting of the i2c bus speedArmando Visconti2012-12-11-15/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are three couple (hcnt/lcnt) of registers for each speed (SS/FS/HS). The driver needs to set the proper couple of regs according to what speed we are setting. Signed-off-by: Armando Visconti <armando.visconti@st.com>
| | | * | designware_i2c: Added s/w generation of stop bitArmando Visconti2012-12-11-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the newer versions of designware i2c IP there is the possibility of configuring it with IC_EMPTYFIFO_HOLD_MASTER_EN=1, which basically requires the s/w to generate the stop bit condition directly, as the h/w will not automatically generate it when TX_FIFO is empty. To avoid generation of an extra 0x0 byte sent as data, the IC_STOP command must be sent along with the last IC_CMD. This patch always writes bit[9] of ic_data_cmd even in the older versions, assuming that it is a noop there. Signed-off-by: Armando Visconti <armando.visconti@st.com>

This algorithm was derived by using a scope, but the result seems correct. The resulting values programmed into the registers do not correlate with the contents in datasheet. When using the values from the datasheet, the I2C clock were completely wrong.

| | | * | mxs: i2c: Restore speed setting after block resetMarek Vasut2012-12-11-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The I2C block reset configures the I2C bus speed to strange value. Read the I2C speed from the block before reseting the block and restore it afterwards, so the I2C operates correctly. This issue can be replicated by doing unsuccessful I2C transfer, after such transfer finishes, the I2C block clock speed is misconfigured.

The problem is that the EC handling port 80 access is orders of magnitude slower than the AP. This causes random loss of trace data. This change allows to throttle port 80 accesses such that in case the AP is trying to post faster than the EC can handle, a delay is introduced to make sure that the post rate is throttled. Experiments have shown that on Link the delay should be at least 350,000 of tsc clocks. Throttling is not being enabled by default: to enable it one would have to set MIN_PORT80_KCLOCKS_DELAY to something like 400 and rebuild the u-boot image. With upcoming EC code optimizations this number could be decreased (new new value should be established experimentally).

| | * | x86: Provide tick counter and frequency reference for Intel core architectureVadim Bendebury2012-12-06-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some u-boot modules rely on availability of get_ticks() and get_tbclk() functions, reporting a free running clock and its frequency respectively. Traditionally these functions return number and frequency of timer interrupts. Intel's core architecture processors however are known to run the rdtsc instruction at a constant rate of the so called 'Max Non Turbo ratio' times the external clock frequency which is 100MHz. This is just as good for the timer tick functions in question. Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will write magic value to APMC command port which will trigger an SMI and cause coreboot to lock down the ME, chipset, and CPU.
