1. Move file, "start_gcc.S", from "libcpu/arm/cortex-m3/" to "bsp/efm32/"
2. Upgrade EFM32 driver libraries (CMSIS and efm32lib) to version 2.2.2
3. Upgrade EFM32 G2xx development kit drivers (EFM32_Gxxx_DK) to version 1.7.2 (from version 1.6.0)
4. Modify the files ("drv_usart.c" and "drv_iic.c") according to the driver libraries upgrading

1. Add the missing file, "mma7455l.h"
2. Modify Ethernet DEMO according to the changes of lwIP API in reversion 1668
git-svn-id: https://rt-thread.googlecode.com/svn/trunk@1680 bbd45198-f89e-11dd-88c7-29a3b14d5316
1. Change the usage of the second parameter of Read and Write functions in IIC driver
- to "Slave address" from (seldom used) "Offset"
2. Add a timer for IIC driver to prevent from forever waiting
3. Add digital (IIC) interface support for accelerometer driver (Freescale MMA7455L)

1. Solve the problem mentioned in revision 1623 (runtime error)
- Cause: In the EFM32 demo application, some TCP/IP functions are called in non-task context (e.g. "tcp_new()"). And after revision 1621, those functions will trigger the scheduler ("rt_schedule()") which seems to be triggered only in task context.

1. Remove "RT_USING_NETUTILS" defined in "rtconfig.h" to avoid compiling error
- Warning: Due to the memory limitation, running lwIP on Gecko devices (EFM32G) is not properly tested.
- Warning: To test lwIP, please revert the file, "components\net\lwip\src\arch\sys_arch.c", to revision 1620. There is a runtime error when working with the latest revision of that file. This error is currently under evaluation.

1. Add ENC28J60 Ethernet controller driver
2. Add lwIP support (Please read "Readme.txt")
3. Add simple Http server demo application
4. Modify USART device write function to avoid sleep in ISR
5. Fix a bug in USART driver when using compiler optimization
6. Modify to make use the start-up code in libraries
7. Change the default build option for squeezing the executable file size
8. Modify source code alignment
git-svn-id: https://rt-thread.googlecode.com/svn/trunk@1622 bbd45198-f89e-11dd-88c7-29a3b14d5316
1. Add SD card driver (SPI mode)
2. Add ELM ChaN FatFs support (Please read "Readme.txt")
- Warning: FatFs is really FAT! (35KB)
3. Upgrade EFM32 libraries (CMSIS and efm32lib) to version 2.0.0
4. Merge all of the C source code in "libcpu\arm\cortex-m3\" into "cpuport.c"
5. Merge all of the assembly source code in "libcpu\arm\cortex-m3\" into "context_gcc.S" (except "start_gcc.S")
git-svn-id: https://rt-thread.googlecode.com/svn/trunk@1525 bbd45198-f89e-11dd-88c7-29a3b14d5316
1. Update the copyright information
- 2009 => 2011
2. Add external oscillator configuration routine in "rt_hw_board_init()"
- Before, it is set by default frequency, 32MHz
- Now it can be set by user specified frequency
3. Add ADC and ACMP (analog comparator) drivers
4. Clarify the MCU and target board define in "rtconfig.py"
