2019-07-15mmc: During a switch, poll on dat0 if available and check the final statusJean-Jacques Hiblot
The switch operation can sometimes make the bus unreliable, in that case the send_status parameter should be false to indicate not to poll using CMD13. If polling on dat0 is possible, we should use it to detect the end of the operation. At the end of the operation it is safe to use CMD13 to get the status of the card. It is important to do so because the operation may have failed. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2019-07-15mmc: When switching partition, use the timeout specified in the ext_csdJean-Jacques Hiblot
The e-MMC spec allows the e-MMC to specify a timeout for the partition switch command. It can take up to 2550 ms. There is no lower limit to this value in the spec, but do as the the linux driver does and force it to be at least 300ms. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2019-07-15mmc: use the generic timeout for cmd6 (SWITCH) provided in the ext_csdJean-Jacques Hiblot
Starting with rev 4.5, the eMMC can define a generic timeout for the SWITCH command. Following Linux Kernel code, the timeout also changed from 1000 -> 500 Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2019-07-15mmc: if possible, poll the busy state using DAT0Jean-Jacques Hiblot
Using the DAT0 line as a rdy/busy line is an alternative to reading the status register of the card. It especially useful in situation where the bus is not in a good shape, like when modes are switched. This is also how the linux driver behaves. Note of warning: As per the specification, while polling on DAT0 the CLK must not turned off: "[...] Without a clock edge the Device (unless previously disconnected by a deselect command (CMD7)) will force the DAT0 line down, forever. [...]" Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2019-07-15mmc: add mmc_poll_for_busy() and change the purpose of mmc_send_status()Jean-Jacques Hiblot
mmc_send_status() is currently used to poll the card until it is ready, not actually returning the status of the card. Make it return the status and add another function to poll the card. Also remove the 'extern' declaration in the mmc-private.h header to comply with the coding standard. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>

2019-07-15mmc: omap_hsmmc: reset FSM for DAT and CMD lines if needed before a new commandJean-Jacques Hiblot
It sometimes happen that the PSTATE register does not indicate that the bus is ready when it really is. This usually happens after a mode switch. In that case it makes sense to reset the FSM handling the CMD and DATA Also reset the FSMs if the STATE register cannot be cleared. This also sometimes happens after a mode switch.

In general we should avoid calling malloc() and free() repeatedly in U-Boot lest we turn it into tianocore.

2019-07-09rtc: pcf2127: Fixed bug with rtc settings and getting error timeChuanhua Han
The previous pcf2127 RTC chip could not read and set the correct time. When reading the data of internal registers, the read address was the value of register plus 1. This is because this chip requires the host to send a stop signal after setting the register address and before reading the register data. This patch sets the register address using dm_i2c_write and reads the register data using the original dm_i2c_xfer in order to generate a stop signal after the register address is set, and fixes the bug of the original read and write time.
