drivers/misc: Add basic support for ATSHA204A Crypto module
This module can be found on the Turris Omnia board connected via the I2C interface. Among some cryptographic functions, the chip has a 512 bit One Time Programmable memory, 88 byte configuration memory and 512 byte general purpose memory. The Turris Omnia stores serial number and device MAC address in the OTP memory. This commit adds basic support for reading the EEPROM and also exposes the chips Random Number Generator. The driver is based on code by Josh Datko, Cryptotronix, jbd@cryptotronix.com and also Tomas Hlavacek, CZ.NIC, tomas.hlavacek@nic.cz Signed-off-by: Tomas Hlavacek <tomas.hlavacek@nic.cz> Signed-off-by: Marek Behun <marek.behun@nic.cz> create mode 100644 drivers/misc/atsha204a-i2c.c create mode 100644 include/atsha204a-i2c.h Signed-off-by: Stefan Roese <sr@denx.de>
