973c2149d4 [ion/battery] Battery level has some hysteresis 
This prevents a blinking battery pictogra wwhen the battery level is at
the limit between two states.

78eea601c7 [ion/device] Prevent the user from leaving DFU during software download 
We prevent the use of the Back key to leave DFU after a flash erase
operation. This way, we prevent the user from interrupting a software
download. After every software download, the calculator resets, which
unlocks the "exit on pressing back"

5b00192b67 [ion/device] Remove ad-hoc compiler optimizations 
Since we hand-specify which regs/regs.h functions shoudl be inlined, we
don't need to depend on specific compiler optimization levels.

d0660b6543 [ion/device] Force inlining compile-time bit ranges 
Most of the time register operations can be optimized to a single
assembly instruction. That being said, aggressive -Os optimization can
lead the compiler to think that factorizing calls to setBitRange is a
good idea.

But we really want register operations to be inlined (and therefore
optimized as a single instruction), so we enforce inlining setBitRange
and REGS_FIELD macros.

b155af0c0d [ion/external_flash] Finer flash sectors 
Instead of 128 sectors of 64K, there are now 8 sectors of 4K, 1 of 32K
and 127 of 64K. This makes a more finely erasable flash, which is needed
for the exam mode.

6762bb05af [ion/cache] Add missing memory barrier 
__asm volatile("nop") creates a memory barrier that prevents a crash on
the flasher.
Scenario: On the n0110, build flasher.bin, flash it at 0x20030000, build
bench.bin, flash it using the flasher at 0x20008000 -> the flasher cannot
make the device jump to the bench and crashes in the method
Ion::Device::Reset::Jump, inside Ion::Device::Cache::disableDCache().
