The correct mapping is:
MTDO > CS
MTCK > MOSI
MTDI > MISO
MTMS > CLK

Thanks for your interest in ESP8266 !

MTDO > CS
MTCK > MOSI
MTDI > MISO
MTMS > CLK

while I say they might be:

MTCK -> SCLK
MTMS -> CS
MTDO -> MOSI
MTDI -> MISO

It seems we disagree on MTDO, MTCK, MTMS ... the only one we agree on is MTDI ...

The HSPI manual is now updated. The correct mapping is:
MTDO > CS
MTCK > MOSI
MTDI > MISO
MTMS > CLK

Thanks again!

download/file.php?id=577

seems confused on the table on page 7:

* Mode reads as "HSPI Defaul IO" ... should be "HSPI Default IO"
* The mappings of pin names on ESP8266 to SPI bus signals is defined as:

MTDO -> CS
MTCK -> MOSI
MTDI -> MISO
MTMS -> CS

This feels wrong ... I am guessing it should be:

MTCK -> SCLK
MTMS -> CS
MTDO -> MOSI
MTDI -> MISO

all in all, very confusing.
