Commit 8dfafdde88eb ("Introduce common timer functions") created a
common definition of usec_to_tick() which had a couple problems:

static unsigned long long usec_to_tick(unsigned long usec)
{
       uint64_t tick = usec * get_tbclk();

That likely overflows.

       usec *= get_tbclk();

promotion of usec to 64-bit, but was applied to the wrong variable,
which was never used.

This patch fixes these issues. A user-visible symptom of the problem was
the e.g. "dhcp zImage" using an ASIX USB Ethernet dongle would print:

Waiting for Ethernet connection... unable to connect.

arm: omap: i2c: don't zero cnt in i2c_write

Writing zero into I2Ci.I2C_CNT register causes random I2C failures in OMAP3
based devices. This seems to be related to the following advisory which
apears in multiple erratas for OMAP3 SoCs (OMAP35xx, DM37xx), as well as
OMAP4430 TRM:

Advisory:
I2C Module Does Not Allow 0-Byte Data Requests
Details:
When configured as the master, the I2C module does not allow 0-byte data
transfers. Note: Programming I2Ci.I2C_CNT[15:0]: DCOUNT = 0 will cause
undefined behavior.
Workaround(s):
No workaround. Do not use 0-byte data requests.

The writes in question are unnecessary from a functional point of view.
Most of them are done after I/O has finished, and the only one that preceds
I/O (in i2c_probe()) is also unnecessary because a stop bit is sent before
actual data transmission takes place.

Therefore, remove all writes that zero the cnt register.

cmd_eeprom: bug fix for i2c read/write

The local pointer of address (i.e., addr) only gets
referenced under SPI mode, and it won't be appropriate
to pass only 1-byte addr[1] to i2c_read/i2c_write while
CONFIG_SYS_I2C_EEPROM_ADDR_LEN > 1.

1. In U-boot's I2C model, the address would be re-assembled
   to a byte string in MSB order inside I2C controller drivers.

2. The 'CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW' option which could
   be found at soft_i2c.c is always turned on in cmd_eeprom.c,
   the addr[0] always contains the device address with overflowed
   MSB address bits.
