Nested init on i.MX31 via base_hw. Rework base_hw. Implies support for the ARMv6 architecture through 'base-hw'. Get rid of 'base/include/drivers' expect of 'base/include/drivers/uart'. Merge with the support for trustzone on VEA9X4 that came from Stefan Kalkowski. Leave board drivers in 'base/include/platform'. Rework structure of the other drivers that were moved to 'base_hw/src/core' and those that came with the trustzone support. Beautify further stuff in 'base_hw'. Test 'nested_init' with 'hw_imx31' (hardware) and 'hw_panda_a2' (hardware), 'demo' and 'signal' with 'hw_pbxa9' (qemu) and 'hw_vea9x4' (hardware, no trustzone), and 'vmm' with 'hw_vea9x4' (hardware, with trustzone). 2012-10-23 15:12:09 +00:00			`SPECS += arm`

hw: switch page-tables only when necessary * Instead of always re-load page-tables when a thread context is switched only do this when another user PD's thread is the next target, core-threads are always executed within the last PD's page-table set * remove the concept of the mode transition * instead map the exception vector once in bootstrap code into kernel's memory segment * when a new page directory is constructed for a user PD, copy over the top-level kernel segment entries on RISCV and X86, on ARM we use a designated page directory register for the kernel segment * transfer the current CPU id from bootstrap to core/kernel in a register to ease first stack address calculation * align cpu context member of threads and vms, because of x86 constraints regarding the stack-pointer loading * introduce Align_at template for members with alignment constraints * let the x86 hardware do part of the context saving in ISS, by passing the thread context into the TSS before leaving to user-land * use one exception vector for all ARM platforms including Arm_v6 Fix #2091 2017-06-30 10:00:27 +00:00			`CC_MARCH += -march=armv6k`

Introduce 'spec' subdirectories to outline aspects Instead of holding SPEC-variable dependent files and directories inline within the repository structure, move them into 'spec' subdirectories at the corresponding levels, e.g.: repos/base/include/spec repos/base/mk/spec repos/base/lib/mk/spec repos/base/src/core/spec ... Moreover, this commit removes the 'platform' directories. That term was used in an overloaded sense. All SPEC-relative 'platform' directories are now named 'spec'. Other files, like for instance those related to the kernel/architecture specific startup library, where moved from 'platform' directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.

base/mk: include sub specs from BASE_DIR Originally, the spec files for less specific SPEC values were include via the 'select_from_repositories' function. This implies that BASE_DIR must always be present in the list of 'REPOSITORIES'. Otherwise the spec files won't be found. By explicitly including sub specs from '$(BASE_DIR)/mk', we lift this restriction. 2017-04-07 08:48:02 +00:00			`include $(BASE_DIR)/mk/spec/arm.mk`
