8f71973918 Coldfire: Properly handle the SDRAM refresh timing on CPU frequency changes. For >= 92 MHz operation, tRC needs to be 6 clocks, otherwise 3 clocks are sufficient.

9322009446 Coldfire: (1) Keep the correct CRSEL and CLSEL values in the PLLCR register for CPUFREQ_DEFAULT. Fixes non-working treble & bass controls in radio screen. (2) Save a bit more power by powering down the PLL at CPUFREQ_DEFAULT.

f6bb10a485 Iriver: No write protection for flash ROM area, correct number of waitstates.

1f39f2e748 Ported the memory guard debug feature to coldfire, using the breakpoint logic. There are 3 shortcomings compared to SH1: (1) While the setting itself survives RoLo, it cannot be read back because the debug module programming model is write only. (2) system_reboot() from a 'Debug' exception doesn't work because the CPU enters emulation mode, and the only way leaving this mode is via an rte instruction. (3) (fixable) Catching write accesses to the flash doesn't actually do anything because the flash memory area is set write protected in CSMR2, so a write attempt stalls the bus. * Cosmetic changes in system.c

cfb073c452 Coldfire: New timer handling on CPU frequency change, adjusting the prescaler on the fly, for both tick and user timer. Precondition is that the higher frequencies are integer multiples of the base: now NORMAL is 45 MHz and MAX is 124 MHz. Removes the need for applications with longer timer periods (>= 10 ms) to boost the CPU all the time, e.g. the grayscale lib. Timer counts are now always based on the base frequency (CPU_FREQ). * Adjusted the RAM refresh timers to the new frequencies (all frequencies for H100) * All: Fixed the tick timer count being off by one.

dc4a6b828e iriver: Moved the I2C prescaler setting to i2c_init(), and removed it from set_cpu_frequency(). The Coldfire I2C controller can't handle on-the-fly prescaler changes. Also removed the unnecessary slave address setting in i2c_init.

038df5cdc9 Daniel, 
The following patch makes loadable fonts actually work (finally!).
It took me quite a while, but I finally figured out why the sim
worked and the target didn't: the SH1 processor won't read
longwords from a shortword alignment... I had to rev the .fnt
file to version 1.1 (requires remaking *.fnt files) in order
to fix this.  Please apply the following patch completely.
It's diffed against the latest CVS.

I've also attached rockbox-fonts-1.1.tar.gz which includes
known working *.fnt files, including a courB08 system.fnt,
for demonstration.

Now the real work can begin...  Although the new
system.fnt will work fine, if you try going to a really
big font (try copying courB14.fnt to system.fnt), then
you will find that it comes up and works in tree mode,
but will crash the system when going into WPS
mode...  I'm sure this is because of the low-level
lcd_bitmap not clipping properly when given a too-large
bitmap, which the characters become.  I haven't yet
tried to debug the low-level driver.  Of course, it all
works on the sim...

So the apps developers will now have to make sure that
all apps screen sizes may vary according to the loaded font.
The font height can be gotten through the lcd_getfontsize API.

Files patched in fonts-6.patch

1. apps/menu.c - LCD_PROPFONTS error (2nd resubmission on this, please checkin)

2. firmware/font.c - fixes and reformatting.  Please check this in as is,
my vi editor requires more reformatting changes since I left tabs in the
file, these are removed now (2nd resubmission on this, please checkin)

3. firmware/fonts.h - doc change on .fnt file format, .fnt version
number incremented.

4. firmware/loadfont.c - fixes to load font properly, typedefs
removed.

5. firmware/system.c - lcd_setfont(FONT_SYSFIXED) before
issuing error, otherwise font may not exist.

6. tools/bdf2c - fixes for correct output when filename starts
with a number, as well as when no DEFAULT_CHAR in .bdf
file.  (2nd resubmission on this, please checkin)

7. tools/writerbf.c - fixes for bugfixed fontfile format.
