Bugfix: make date/time setting work over reboots
Setting the time/date over the UART interface or by the menu, seems
to work, but a reboot of the RTE brings back strange, seemingly
random, time.
The reason for this is rather simple. In the settings, a time
is stored, based on some flawed logic, and that time was restored
on reboot. There is no reason to store any time, when the moment of
restoring it is unrelated in time. So, the fix is simple: do not
set time (in the RTC) based on some time from the past. The whole idea
of a RTC is that it does preserve the time for you, as long its
powered. Any attempt to do things better using stored time data is
futile (and nonsense).
And while working on his, also kick out some useless code from the RTE.
There is no reason to initialize the time on the RTC to some random
time/date in the past. A zero data/time is as good and any random
date.

/** ****************************************************************************** * @file stm32f4xx_hal_cryp.c * @author MCD Application Team * @brief CRYP HAL module driver. * This file provides firmware functions to manage the following * functionalities of the Cryptography (CRYP) peripheral: * + Initialization and de-initialization functions * + AES processing functions * + DES processing functions * + TDES processing functions * + DMA callback functions * + CRYP IRQ handler management * + Peripheral State functions * @verbatim ============================================================================== ##### How to use this driver ##### ============================================================================== [..] The CRYP HAL driver can be used as follows: (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit(): (##) Enable the CRYP interface clock using __HAL_RCC_CRYP_CLK_ENABLE() (##) In case of using interrupts (e.g. HAL_CRYP_AESECB_Encrypt_IT()) (+++) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority() (+++) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ() (+++) In CRYP IRQ handler, call HAL_CRYP_IRQHandler() (##) In case of using DMA to control data transfer (e.g. HAL_CRYP_AESECB_Encrypt_DMA()) (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE() (+++) Configure and enable two DMA streams one for managing data transfer from memory to peripheral (input stream) and another stream for managing data transfer from peripheral to memory (output stream) (+++) Associate the initialized DMA handle to the CRYP DMA handle using __HAL_LINKDMA() (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the two DMA Streams. The output stream should have higher priority than the input stream HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ() (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly: (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit (##) The key size: 128, 192 and 256. This parameter is relevant only for AES (##) The encryption/decryption key. It's size depends on the algorithm used for encryption/decryption (##) The initialization vector (counter). It is not used ECB mode. (#)Three processing (encryption/decryption) functions are available: (##) Polling mode: encryption and decryption APIs are blocking functions i.e. they process the data and wait till the processing is finished, e.g. HAL_CRYP_AESCBC_Encrypt() (##) Interrupt mode: encryption and decryption APIs are not blocking functions i.e. they process the data under interrupt, e.g. HAL_CRYP_AESCBC_Encrypt_IT() (##) DMA mode: encryption and decryption APIs are not blocking functions i.e. the data transfer is ensured by DMA, e.g. HAL_CRYP_AESCBC_Encrypt_DMA() (#)When the processing function is called at first time after HAL_CRYP_Init() the CRYP peripheral is initialized and processes the buffer in input. At second call, the processing function performs an append of the already processed buffer. When a new data block is to be processed, call HAL_CRYP_Init() then the processing function. (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral. @endverbatim ****************************************************************************** * @attention * * <h2><center>© COPYRIGHT(c) 2017 STMicroelectronics</center></h2> * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
