		2) Bugfix: Partition-Size-Setting in bfmt-command.
		3) Bugfix: Very first store of XIP-image fails.
		4) Bugfix: misconfigured GPIO-pins draw high current during boot-phase.
=======================================================================================================
03.01.2012	1) Bugfix: Internal configuration of all IO-voltages (VDDIO) to 3,3V.
		2) Added !pwr and @pwr commands to read/write to PMIC.
		3) Bugfix: Display does not always get initialized (only seen with special timing).
=======================================================================================================
12.04.2012	1) Increased (slower) csdficfg0-timing ( address/data-bus).
		2) DPF-932: Set AFIFO_MERGE_DIS in CPU_CONF-register.
=======================================================================================================
27.04.2012	1) Changed to Loader 3_2_29.
		2) Bugfix: If power is removed during suspend, system may hang if power is re-applied
			in 2..10 seconds
=======================================================================================================
15.06.2012	1) Added ClockDivider -option. If bit 0x8000 is set, clock display-controller with
                   624MHz instead of 312MHz.
                2) Added _Bootloader -string. This is passed to WinCE and can be read from registry at 
                   [HKLM\System\KuK\Boot]
=======================================================================================================
06.07.2012	1) Added 'eeprom' command/device
		2) Added 'displayeprom' command
=======================================================================================================
11.07.2012	1) Added/fixed option to check external CPLD-register if to resume from hibernate.
=======================================================================================================
25.07.2012	1) Support for NANYA 128MB DDR2 RAM.
=======================================================================================================
04.12.2012	1) Support for V1R2-Revision of Trizeps VI. (CLK-pin of uSD-slot changed).
=======================================================================================================
24.01.2013      1) Bugfix: If SD-Card is not inserted boot/mount will take 10seconds longer.
=======================================================================================================
18.10.2013	1) Improved boot-speed from nanddisk.
		2) Added .png/APNG support.
		3) Added storearg command to store bootloader-configuration.
		   Added bootloader-configuration variables:
		   verbose		(0: serial for app, 1: serial for debug)
		   OPrun, OPmax, OPmin	(Run, Maximum and Minimum operating point: 0=156MHz, 1=400MHz, 2=624MHz, 3=800MHz, 4=1066MHz)
		   IPMmode:
			IPM_ENABLED               = 0x0001,   // IPM Enabled
			IPM_DFVM_ENABLED          = 0x0002,   // Enable DFVM
    			IPM_LPM_SYSTEM_SLEEP      = 0x0020,    
			IPM_LPM_APP_SUBSYSTEM_SLEEP = 0x0040,
			IPM_LPM_APP_SUBSYSTEM_IDLE = 0x0080,
 			IPM_LPM_DDR_SR            = 0x0400,
=======================================================================================================
21.07.2015	1) Bugfix: Hang if Bad-Block-Table corrupt.
                   Bootloader will now boot and try to fix Bad-Block-Table.
=======================================================================================================
07.11.2016      1) Count Bit-errors during boot and store them to "DoubleBitError" and "SingleBitError"
17.11.2016	2) Added _mod Version which will change default pull-up behaviour of 
		   LCD_BIAS,CLK,HSYNC,VSYNC,LDD00-LDD17 pins
		   to pull-down as soon as possible during boot.
=======================================================================================================
19.01.2017      1) Fix: Under special cirumstances "DoubleBitError" is not counted. (SBE near DBE).
=======================================================================================================
17.08.2017      1) Fix: Bootloader hangs on Cold-Boot
                   After power-on the RAM-contents is undefined.
                   If the RAM got an affinity to have 0x55AA55AA as content, this is interpreted by the
                   Boot-ROM as resume and it would try to start an non-existing resume-handler in RAM.
=======================================================================================================
31.08.2017	1) Fix for 17.08.2017. Workaround had problems on some Trizeps VI modules.
=======================================================================================================
05.04.2018	1) Fix: If Manufacture-Time (_Manufacture) is shorter than 24 bytes, 
                   than the Bootloader-Version (_Bootloader, typ. 20bytes) will lose the last byte(s)
                   of the version-info.
                   This would usually happen, if the milliseconds in the manufacture-time is less than 100.
