This patch updates ST's HAL to the latest version, V1.3.0, dated 19 June 2014. Files were copied verbatim from the ST package. Only change was to suppress compiler warning of unused variables in 4 places. A lot of the changes from ST are cosmetic: comments and white space. Some small code changes here and there, and addition of F411 header. Main code change is how SysTick interrupt is set: it now has a configuration variable to set the priority, so we no longer need to work around this (originall in system_stm32f4xx.c).

*** ARM Compiler ***
|
|
--------------------
|
|
[..] RAM functions are defined using the toolchain options.
|
|
Functions that are be executed in RAM should reside in a separate
|
|
source module. Using the 'Options for File' dialog you can simply change
|
|
the 'Code / Const' area of a module to a memory space in physical RAM.
|
|
Available memory areas are declared in the 'Target' tab of the
|
|
Options for Target' dialog.
|
|
|
|
*** ICCARM Compiler ***
|
|
-----------------------
|
|
[..] RAM functions are defined using a specific toolchain keyword "__ramfunc".
|
|
|
|
*** GNU Compiler ***
|
|
--------------------
|
|
[..] RAM functions are defined using a specific toolchain attribute
|
|
"__attribute__((section(".RamFunc")))".
