<font color='#000088'>+Clock Speed Determination Algorithm
+===================================
+Till Straumann submitted a patch to provide more dynamic clock speed
+selection.<span style="background-color: #FF0000"> </span>
+
+Currently, the uC5282 BSP requires relinking the application with a
+special linker flag in order to make it work with 80MHz boards (breaking
+run-time compatibility with 64MHz variants).
+
+The change aims adds support for run-time guessing/setting of
+the system-clock frequency:
+
+1) If uCbootloader environment variable SYS_CLOCK_SPEED is set to a
+non-zero number then the BSP assumes this number to specify the clock
+frequency in Hz.
+
+2) If 1) yields no non-zero frequency then the linker-provided symbol
+_CPUClockSpeed is assumed to specify the clock frequency (in Hz). This
+is the traditional behavior but the default value of _CPUClockSpeed
+was changed from 64000000 to 0 (in order to let step 3) do it's work
+by default).
+
+3) If neither 1) nor 2) yield a non-zero frequency then assume a PLL
+reference frequency (in Hz) as defined by the linker-provided symbol
+'_PLLRefClockSpeed' (which defaults to 8000000) and compute the system
+clock frequency from the divisor/multiplier settings in the SYNCR
+register.
+
+We have both, 64MHz and 80MHz variants and both use a PLL reference of
+8MHz so that run-time heuristics + detection 3) work fine.

<font color='#000088'>+Clock Speed Determination Algorithm
+===================================
+Till Straumann submitted a patch to provide more dynamic clock speed
+selection.<span style="background-color: #FF0000"> </span>
+
+Currently, the uC5282 BSP requires relinking the application with a
+special linker flag in order to make it work with 80MHz boards (breaking
+run-time compatibility with 64MHz variants).
+
+The change aims adds support for run-time guessing/setting of
+the system-clock frequency:
+
+1) If uCbootloader environment variable SYS_CLOCK_SPEED is set to a
+non-zero number then the BSP assumes this number to specify the clock
+frequency in Hz.
+
+2) If 1) yields no non-zero frequency then the linker-provided symbol
+_CPUClockSpeed is assumed to specify the clock frequency (in Hz). This
+is the traditional behavior but the default value of _CPUClockSpeed
+was changed from 64000000 to 0 (in order to let step 3) do it's work
+by default).
+
+3) If neither 1) nor 2) yield a non-zero frequency then assume a PLL
+reference frequency (in Hz) as defined by the linker-provided symbol
+'_PLLRefClockSpeed' (which defaults to 8000000) and compute the system
+clock frequency from the divisor/multiplier settings in the SYNCR
+register.
+
+We have both, 64MHz and 80MHz variants and both use a PLL reference of
+8MHz so that run-time heuristics + detection 3) work fine.
